Elbow tendonitis typically resolves with a combination of rest, targeted exercises, and pain management, though full recovery often takes several months. The two most common forms are lateral epicondylitis (tennis elbow), affecting the outside of the elbow, and medial epicondylitis (golfer’s elbow), affecting the inside. Both involve irritation of the tendons that connect your forearm muscles to the bony bumps at your elbow. The good news: most cases respond well to conservative treatment without surgery.
Identify Which Type You Have
Where exactly the pain sits tells you which tendons are involved, and that matters for treatment. Lateral epicondylitis affects the extensor muscles on the outside of your forearm, the ones you use to straighten your wrist and grip. Pain on the outer elbow that worsens when you lift, twist a doorknob, or shake hands points to this type. Medial epicondylitis involves the flexor muscles on the inside of your forearm, used for gripping and wrist curling. Pain on the inner elbow during throwing, squeezing, or pulling motions is the telltale sign.
Both types develop from repetitive strain rather than a single injury. Despite the nicknames, you don’t need to play tennis or golf to get them. Typing, using a mouse, painting, cooking, and manual labor are common triggers.
Rest and Activity Modification
The first step is reducing the load on the affected tendon. That doesn’t mean immobilizing your arm completely, which can actually slow healing by causing stiffness and muscle weakness. Instead, identify the specific motions that provoke your pain and find ways to reduce or modify them. If mouse use is a trigger, switch to your other hand or use a vertical mouse. If gripping is the problem, use tools with larger, padded handles that require less force.
Ice the painful area for 15 to 20 minutes a few times a day, especially after activity. This helps manage pain and any swelling in the early stages.
Pain Relief With Anti-Inflammatories
Over-the-counter anti-inflammatory gels applied directly to the skin over the elbow are a strong first choice. Topical formulations deliver the drug right where it’s needed while producing blood levels that are less than 1% to 2.2% of what you’d get from taking the same medication as a pill. That’s a meaningful difference for your stomach and kidneys. Oral anti-inflammatories taken regularly for five or more days at least twice a year carry more than four times the risk of gastrointestinal problems compared to not taking them at all. Topical versions haven’t been linked to those same gut or kidney issues.
If you do use oral anti-inflammatories, keep them short-term for flare-ups rather than relying on them daily for weeks.
Exercises That Actually Help
Eccentric strengthening is the single most effective exercise approach for elbow tendonitis. Eccentric means loading the muscle while it lengthens, essentially the “lowering” phase of a movement. For lateral epicondylitis, this involves slowly lowering a light weight with your wrist extended over the edge of a table, palm facing down. For medial epicondylitis, you do the same motion but with your palm facing up.
Start with a weight light enough that you can do 3 sets of 15 repetitions with only mild discomfort, not sharp pain. Increase the weight gradually over weeks. Most rehab programs run 6 to 12 weeks before significant improvement kicks in, so patience matters here. Stretching the forearm extensors and flexors gently before and after exercise sessions helps maintain flexibility.
Grip strengthening with a soft squeeze ball or therapy putty is also useful once the initial sharp pain has settled. Weak forearm muscles fatigue quickly and shift more stress onto the tendons, so building overall forearm strength is part of long-term prevention.
Bracing for Symptom Control
A counterforce brace (the strap-style band you wear on your forearm) can reduce pain during activities by dispersing the force before it reaches the tendon attachment point. Position the strap about 1 to 2 inches below the bony bump on the outside (or inside) of your elbow, depending on which type you have. It should be snug but not tight enough to cause numbness or tingling in your hand.
Wear the brace during aggravating activities, not all day. Relying on it constantly can mask pain signals that help you gauge your recovery, and it doesn’t replace strengthening exercises.
Injection Options for Stubborn Cases
When conservative measures aren’t cutting it after several weeks, injection therapy is worth discussing with a provider. The two most common options are corticosteroid injections and platelet-rich plasma (PRP) injections, and they work on very different timelines.
Corticosteroid injections provide faster relief, typically within 2 to 8 weeks, by reducing inflammation at the tendon. The downside is that the benefit tends to fade. PRP injections, which use a concentrated sample of your own blood platelets to stimulate healing, take longer to show results but outperform corticosteroids for long-term pain relief, function, and disability scores beyond the 8-week mark. Systematic reviews consistently show PRP is the better option when lasting improvement is the goal.
One important caveat: repeated corticosteroid injections can weaken tendon tissue over time, so most providers limit them to two or three in the same area.
Shockwave Therapy
Extracorporeal shockwave therapy (ESWT) uses targeted sound waves to stimulate blood flow and healing in the tendon. It’s typically reserved for cases that haven’t responded to other treatments. A standard protocol involves three weekly sessions, each delivering around 2,000 pulses of energy to the affected area. Sessions last about 10 to 15 minutes and can be uncomfortable during treatment, though the discomfort is brief.
Results from clinical trials are mixed. Some patients experience meaningful pain reduction, while others see little benefit. It’s more commonly available through sports medicine and physical therapy clinics than through general practitioners.
Workstation Setup for Prevention
If your tendonitis is connected to desk work, your workstation setup can either help you heal or keep re-injuring the tendon. Your keyboard and mouse should sit at or slightly below elbow height, with your elbows bent between 90 and 110 degrees and your shoulders relaxed. Your upper arms should hang naturally at your sides rather than reaching forward or out to the side.
Keep your wrists in a neutral position, not bent upward or angled to one side. A keyboard tray that tilts slightly downward (negative tilt) and a padded wrist rest can help. If you use a mouse heavily, alternate hands periodically or consider a trackpad to vary the movement pattern. Taking short breaks every 30 to 45 minutes to stretch your forearms makes a noticeable difference over weeks.
When Surgery Becomes an Option
Surgery is only considered after at least 12 months of failed conservative treatment. That’s a long runway, but it reflects the fact that the vast majority of elbow tendonitis cases resolve without an operation. The procedure involves removing the damaged portion of tendon and, in some cases, reattaching healthy tissue to the bone. Recovery from surgery typically takes 3 to 6 months before full activity resumes.
If your pain is manageable and gradually improving with exercise and load management, staying the course with conservative treatment is almost always the right call. The tendon needs time to remodel, and the exercises work cumulatively over months rather than weeks.
