Elbow Pain During Push-Ups: Managing Tricep Tendinopathy and Using NIR for Recovery

If you have ever pushed through the last few reps of a set of push-ups and felt an ache or a sharp catch at the back of your elbow, right at the bony point just above the olecranon, tricep tendinopathy is a reasonable thing to suspect. It gets far less attention than shoulder or wrist pain, but it is a common overuse injury among people who do a lot of bodyweight pressing, bench press, and dips. The mechanism is mechanical rather than mysterious: at the very end of elbow extension, the lockout position, the tricep tendon is pulled tight against the olecranon at the same moment it gets compressed against the bone underneath it, and that combination of pulling and pinching, repeated set after set, is what irritates the tissue.

Since home training took off, more people started relying on bodyweight pressing only, and reports of this specific ache at the back of the elbow rose along with it. It shows up often in people who used to train at a gym with a bench and shifted most of their pressing volume onto push-ups, and in people following daily push-up challenge routines that ramp the rep count up week over week. In both cases, the jump in tendon load happens faster than anyone notices, because push-ups feel like the safe, no-equipment option. Ignore the ache long enough and it can move from a minor nuisance into a more stubborn, chronic tendon problem, so getting the mechanism right early changes how fast this actually resolves.

This guide walks through why tricep tendinopathy develops, what to change about push-up form, and a staged plan for getting back to full training, plus where a near-infrared (NIR) wellness device fits in as a supporting habit rather than a treatment.

Why the Back of Your Elbow Hurts: What Tricep Tendinopathy Actually Is

The triceps brachii has three heads, long, lateral, and medial, that converge into a single tendon attaching at the olecranon, the bony prominence at the top of the ulna. Every movement that straightens the elbow, the top of a push-up, a bench press lockout, the final inch of a dip, loads this tendon with repeated eccentric and isometric stress. The complication is that full elbow extension locks the joint and adds a compressive load on top of that, the tendon gets pressed against bone at the exact moment it is under tension. A similar friction mechanism shows up at the shoulder, where a narrowed subacromial space pinches the supraspinatus tendon in rotator cuff tendinopathy, and something equivalent happens at the olecranon.

Not Just Inflammation: A Change in the Tendon Structure Itself

Tendon pain used to be labeled tendinitis and explained purely as inflammation. That changed after Cook and Purdam (2009) proposed the tendinopathy continuum model, which is now the standard way to think about it: reactive tendinopathy, then tendon disrepair, then degenerative tendinopathy. In the early reactive stage, a sudden jump in load causes the collagen matrix to swell, and that swelling is what hurts. Keep pushing through it and the collagen fibers lose their organized alignment while new blood vessels and nerve endings grow into the tissue, the degenerative stage. This is the reason grinding out more push-up reps against the pain usually delays recovery instead of building tolerance.

A Different Location and a Different Mechanism Than Tennis Elbow

Elbow pain gets attributed to tennis elbow (lateral epicondylitis) or golfer's elbow (medial epicondylitis) by default, but those occur where the wrist muscles attach on the outside or inside of the elbow. Tricep tendinopathy sits at the back, at the tendon insertion just above the bony point you feel when you bend your arm. Location alone usually separates the two. Tricep tendinopathy also tends to flare with elbow flexion and extension, particularly full extension against resistance, rather than with wrist movement, and palpation typically finds tenderness localized to a spot one to two centimeters above the olecranon tip. Tennis elbow and golfer's elbow flare with gripping or bending the wrist; tricep tendinopathy tends to reproduce with straight-arm pushing motions, pushing open a heavy door, lifting something overhead, pressing up off a couch with a locked arm.

Why the Tendon Insertion Specifically

The spot where a tendon meets bone, the enthesis, is a fibrocartilage transition zone rather than ordinary tendon tissue, and it is less vascularized than the tendon body a few centimeters away. It also has to handle tension and compression at the same time, tension from the muscle pulling and compression from the bone underneath during full extension, a combination that plain tendon mid-substance rarely deals with. That combined load is why overuse pressing injuries so often show up right at the insertion rather than in the muscle belly or the middle of the tendon, and it is also why insertional tendinopathy tends to respond more slowly to the same rehab exercises that work well for mid-tendon problems.

Common Triggers

• Volume spikes: pushing sets or reps up more than 30 percent within two to three weeks
• Overusing the lockout: locking the elbow fully on every single rep, especially in dips and bench press
• Uneven hand position: a grip noticeably wider than shoulder width, which increases valgus stress at the elbow
• Not enough recovery: stacking tricep-heavy sessions, push-ups, dips, overhead pressing, back to back with no gap
• Skipping the warm-up: going straight into a hard set with cold tissue
• Surface angle: too many incline push-ups with the hands higher than the torso, which concentrates load at the end range of extension
• Narrow-grip dips: the closer the bars, the more the triceps take over the movement, and the sharper the jump in tendon load

A similar warm-up gap in the low back produces a comparable pain pattern worth knowing about: morning low back pain

Fixing Your Form and a Staged Recovery Protocol

The point of managing tricep tendinopathy is not eliminating pain completely before you go back to training, it is reintroducing load gradually, inside a range the tendon can tolerate. Complete rest only makes sense briefly, during the acute flare. After that, a staged reloading plan like the one below gets you back faster than waiting for zero pain.

Form Checklist

1) Set your hand position at shoulder width or slightly narrower so your wrist, elbow, and shoulder stack in a line. 2) Practice a soft lockout, stopping five to ten percent short of full extension instead of locking out hard every rep. 3) Keep your elbows from flaring past roughly 45 degrees off your torso on the way down. 4) Rest 60 to 90 seconds between sets, and stop that day's sets once pain crosses 3 out of 10 on a simple scale. 5) Point your fingers forward and check that your wrists are not cocked back excessively under load.

Warm-Up and the Routine Around a Session

Raise your general body temperature with about five minutes of light cardio before the main sets, then add ten pain-free reps of elbow flexion and extension as dynamic prep. Follow that with about ten light band tricep extensions to pre-load the local tissue, which takes the edge off the load spike the tendon otherwise absorbs in the working sets. After training, ice the area for ten to fifteen minutes, or use NIR light exposure, covered below, as part of the same recovery routine.

During this phase, many people add heat or near-infrared light exposure around the tricep tendon to support local circulation and tissue conditioning. Near-infrared light around 850 nanometers is understood to reach past the surface layer into somewhat deeper tissue, and gets used to raise local blood flow and tissue temperature for conditioning purposes before and after a rehab session. It is not a treatment that repairs the tendon structure itself, though, so treat it as a wellness habit layered around the rehab routine rather than the rehab itself, in short doses of five to ten minutes before training and ten to fifteen minutes after. The same load-adjustment logic applies to lower-body pain management: knee pain load management

Load Differences Between Exercises

The same tricep-extension pattern loads the olecranon differently depending on the exercise. A standard push-up spreads roughly 60 to 70 percent of bodyweight across the upper body, with only part of that concentrated at the tendon during lockout. Diamond push-ups and narrow-grip dips keep the elbow tucked against the torso through the whole range, which raises how much of the work the triceps do alone and, with it, how much load the tendon takes. During a painful stretch, set diamond push-ups and narrow-grip dips aside and rehab with standard-grip push-ups or wall push-ups instead, where the load is shared more broadly across the shoulder and chest.

Mistakes That Slow Recovery Down

A few patterns show up repeatedly in people who take longer than expected to recover. Going back to full-lockout dips the moment resting pain hits zero is one: pain-free at rest does not mean the tendon has finished remodeling, and testing under a light load first catches this before a full session does. Swapping push-ups for an unrelated isolation exercise instead of just reducing the volume of the same movement is another: tendons adapt to the specific pattern they are loaded with, so cutting sets and reps of the same exercise works better than avoiding it altogether. Icing right before training, on the assumption it prevents pain, is a third: cold tissue right before loading can make it less pliable, so ice belongs after the session, not before it.

When to Move to the Next Stage, and When to Step Back

Move to the next stage only once an end-range isometric hold produces no more than mild discomfort across two sessions in a row, not just one good day. If pain the morning after a session is higher than it was the day before, that is the signal to drop back a stage and extend the recovery window rather than pushing ahead on schedule.

What Changes to Expect During Recovery

Tendon tissue gets a noticeably smaller blood supply than muscle or ligament, so it heals on a slower timeline by nature. Malliaras and colleagues (2013) reviewed heavy slow resistance protocols and found that progressive loading programs sustained for around 12 weeks meaningfully improved pain and function scores, measured with the VISA questionnaire, in region-specific tendinopathies such as patellar tendinopathy. Silbernagel and colleagues (2007) studied Achilles tendinopathy and found that a group who kept loading the tendon while staying under a pain threshold of 5 out of 10 returned to sport faster than a group that took early complete rest, which gives a reasonable basis for applying the same pain-monitoring principle to a tricep tendon. The mechanism is the same either way: repeated loading within a tolerable pain range is what actually drives the tendon to remodel.

Recovery Timeline by Stage

1. Weeks 1-2: less pain during daily tasks like getting dressed or carrying bags, reduced tenderness on isometric holds
2. Weeks 2-4: complete low-intensity eccentric work pain-free, range of motion largely restored
3. Weeks 4-8: resume full-range push-ups at low volume, a pain-free lockout becomes possible
4. Weeks 8-12: return to full-intensity dips, bench press, and high-intensity push-ups, keep increasing volume from there

A Sample Supplementary Exercise Progression

In the isometric stage, start with a 90-degree wall or doorframe press held for five to ten seconds, repeated eight to ten times. Moving into stage three, band or light dumbbell tricep kickbacks and overhead extensions for 12 to 15 reps per set, staying inside a pain-free range and slowing the eccentric phase to three or four seconds, is a practical way to load the tendon without spiking symptoms. In stage four, progress from knee push-ups to standard push-ups to narrow-grip push-ups, and keep the weekly increase in total reps to around 10 percent over the previous week, since that pacing is what actually keeps flare-ups from coming back.

Tracking Progress Objectively

Run the same provocation test once a week under identical conditions, holding full elbow extension for five seconds, and score it zero to ten. Watching that number over a few weeks shows the actual recovery curve. If the score plateaus or climbs, drop back a stage and extend the recovery window instead of forcing the next one on schedule; pushing ahead without a stable downward trend tends to lengthen the total recovery time, not shorten it. It also helps to note whether pain from a session is still present the next morning, the 24-hour rule, as a check on whether the previous day's volume was actually appropriate.

Daily Habits That Prevent This From Coming Back

Getting back to full intensity is not the finish line, since dropping the load management habits right after tends to invite a repeat. Avoid stacking tricep-dominant sessions, dips or diamond push-ups, on back-to-back days, and keep at least 48 hours between them. When shoulder or wrist mobility is limited, the elbow tends to compensate and absorb extra load, so keeping shoulder external rotation and wrist extension mobility work in the regular warm-up is a long-term habit worth building. Building forearm and lat endurance alongside the triceps, rather than training the triceps in isolation, also spreads the load out instead of concentrating it at one joint, which pays off over months of training rather than in any single session.

This kind of tendon irritation is not confined to the gym. Pushing yourself up off the arm of a couch or a chair with one locked elbow, resting your full weight on a straight arm at a standing desk, lifting a stroller or a car seat repeatedly with the elbow locked out, or sleeping on your side with the elbow bent tightly under a pillow all load the same tendon insertion in smaller, quieter doses throughout the day. None of these need to stop outright, but small changes help: push up off furniture with two hands instead of one locked arm, avoid resting your full bodyweight on a locked elbow at a desk for long stretches, switch which arm carries a heavy bag or a car seat rather than always using the same one, and if side-sleeping is making mornings worse, try keeping the arm less sharply bent or supporting it with a pillow.

Warning Signs and When to See a Doctor

Most tricep tendinopathy improves within 8 to 12 weeks of volume management and progressive reloading. See an orthopedic or sports medicine specialist rather than continuing to self-manage if any of the following show up:

• A sudden pop with immediate loss of extension strength (possible tendon rupture)
• Pain that persists at rest, especially night pain that disrupts sleep
• Visible swelling, warmth, or redness around the olecranon
• No improvement at all after four or more weeks of consistent load management and rehab
• Numbness or tingling that suggests ulnar nerve involvement rather than tendon pain
• Elbow extension strength that feels noticeably weaker even when lifting light objects
• Fever together with visible redness and warmth around the elbow, which can point to a joint or bursa infection rather than tendinopathy

What a Clinical Exam Usually Checks

A first visit typically involves a history, palpation, and a resisted extension test. If the picture is unclear or a rupture is suspected, musculoskeletal ultrasound or MRI checks the tendon's thickness, looks for partial tears, and checks for calcification. Ultrasound is relatively inexpensive and shows the tendon moving in real time, which is why sports medicine clinics often use it as the first-line check. In more severe cases, shock wave therapy or an ultrasound-guided injection may be added to the plan, so discuss the treatment path with the clinician once a diagnosis is confirmed rather than guessing at next steps on your own.

NIR Safety Notes

• Do not shine it directly into the eyes, and wear protective goggles if needed
• If you are taking a photosensitizing medication, tetracycline antibiotics or amiodarone among them, check with your physician before use
• Stop use immediately if ongoing redness or blistering appears on the skin
• Avoid use over open wounds or areas of significant acute swelling until symptoms settle
• An NIR device is a wellness support tool, not a medical device that treats the tendon damage itself; see a specialist if pain persists or gets worse

Managing tricep tendinopathy well is not about total rest, it is a balanced approach that respects pain signals while still giving the tendon consistent, appropriate stimulus. Holding to three things, form correction, progressive loading, and adequate recovery time, while bringing in professional help when it is warranted, is the most reliable path back to pressing without pain.
