Tennis elbow improves for most people with a combination of rest, targeted exercises, and simple home treatments. The condition affects a specific forearm tendon just below the outer elbow, and despite its clinical name (lateral epicondylitis), it’s not actually an inflammatory problem in most cases. It’s a degenerative breakdown of the tendon’s collagen fibers, which changes how you should approach treatment.
Why It Hurts and Why It Lingers
The primary problem is in the tendon of a forearm muscle that controls wrist extension, located about 1 to 2 centimeters below where it attaches to the bony bump on the outside of your elbow. Under a microscope, the tissue typically shows disorganized collagen and degeneration rather than the redness and swelling you’d expect from a true inflammation. This matters because treatments aimed at reducing inflammation (like ice and painkillers) can help with symptoms but don’t fix the underlying tissue damage.
The area also has relatively poor blood supply, which makes it slow to heal and prone to recurring problems. That’s why tennis elbow can drag on for months, and why active rehabilitation through exercise tends to outperform passive treatments over time.
Exercises That Rebuild the Tendon
The single most effective long-term treatment is a specific type of strengthening called eccentric exercise, where you slowly lower a weight or resistance rather than lifting it. This controlled loading stimulates the tendon to remodel and lay down healthier collagen fibers. One popular method, the Tyler Twist, uses a flexible rubber bar that you twist with the injured hand and slowly release. A typical protocol involves three sessions per week for at least four weeks, with each session lasting around 20 minutes.
To do a basic eccentric wrist exercise without special equipment, hold a light dumbbell (1 to 3 pounds) with your forearm resting on a table, palm facing down, and your wrist hanging over the edge. Use your other hand to help lift the weight up, then slowly lower it over a count of three to five seconds using only the injured arm. Three sets of 15 repetitions is a common starting point. You should feel mild discomfort but not sharp pain. If it’s painless, gradually increase the weight.
These exercises can feel counterintuitive when your elbow already hurts, but the progressive loading is what drives tissue repair. Expect gradual improvement over six to twelve weeks rather than immediate relief.
Ice, Heat, and When to Use Each
If your pain flared up recently after a specific activity, ice is the better choice. Apply an ice pack wrapped in a cloth for 15 to 20 minutes every four to six hours to reduce pain and any swelling. Never place ice directly on skin.
For ongoing, chronic tennis elbow (which is the more common scenario), heat is generally more helpful. It increases blood flow to the area, which supports healing in a tendon that already has limited circulation. Heat also relaxes the forearm muscles that pull on the damaged tendon. A warm towel or heating pad before your exercises can make them more comfortable and effective.
Pain Relief Gels and Tablets
Anti-inflammatory gels applied directly to the skin over the outer elbow can provide moderate relief. In clinical data reviewed by Cochrane, people using a topical anti-inflammatory gel rated their pain about 1.6 points lower on a 10-point scale after four weeks compared to a placebo gel. About 73 out of 100 people using the active gel reported improvement, versus 49 out of 100 using a placebo. The main side effect is occasional skin irritation at the application site.
Oral anti-inflammatory tablets are less clearly beneficial for tennis elbow specifically, and they come with a higher risk of stomach pain and digestive side effects. If you’re going to use an anti-inflammatory, the topical version applied directly to the elbow is a reasonable first choice since it delivers the medication locally with fewer systemic effects.
Why Steroid Injections Can Backfire
Corticosteroid injections are one of the most commonly offered treatments, and they do work impressively well in the short term, typically providing significant relief within six to eight weeks. But the long-term picture is less encouraging. In a clinical trial comparing steroid injections to placebo injections, the steroid group showed only 83% recovery at one year compared to 96% in the placebo group. The steroid itself appeared to be responsible for higher recurrence rates and delayed overall recovery.
This doesn’t mean injections are never appropriate. For someone in severe pain who needs short-term function (a musician before a performance, for example), the trade-off might be worth it. But for most people, injections are best avoided as a first-line treatment when exercise-based rehabilitation can produce better and more durable results.
Braces and Straps
A counterforce brace, the strap you see people wearing just below the elbow, works by redistributing the pull of the forearm muscles away from the damaged tendon. It essentially creates a new anchor point for the muscles, reducing the load on the injured attachment. Place it about 4 centimeters (roughly two finger-widths) below your elbow crease and tighten it until it feels snug but not uncomfortable.
These braces are most useful during activities that aggravate your pain, like gripping, typing, or lifting. They’re a symptom-management tool rather than a cure, so use them alongside your exercise program rather than instead of it.
Adjusting Your Desk Setup
If you work at a computer, your workstation may be feeding the problem. Typing and mousing with your wrist extended or your arm reaching forward puts continuous strain on exactly the tendon that’s damaged. Three adjustments make the biggest difference:
- Elbow angle: Your forearms should form a 90-degree angle with your upper arms while typing. If your forearms angle upward or downward, adjust your chair height or keyboard position.
- Mouse placement: Keep your mouse at your side with your arm close to your body, not reaching forward or out to the side.
- Wrist position: Your hands should be level with the keyboard. If they’re not, a wrist pad can bridge the gap and keep your wrists neutral.
These changes reduce the constant low-grade loading that prevents your tendon from recovering between exercise sessions.
Platelet-Rich Plasma Therapy
PRP therapy involves drawing your blood, concentrating the platelets (which contain growth factors), and injecting them into the damaged tendon. It’s typically considered after several months of failed conservative treatment. A systematic review in the Journal of Shoulder and Elbow Surgery found success rates ranging widely, from 70% to 100% depending on the preparation method used. Results tend to build gradually over weeks to months rather than providing immediate relief.
PRP is not covered by most insurance plans and costs several hundred dollars per injection. The evidence is promising but still evolving, so it’s best viewed as a second-tier option after a solid exercise program has been given a fair trial of at least three months.
Shockwave Therapy
Extracorporeal shockwave therapy delivers focused sound wave pulses to the tendon to stimulate healing. It’s typically administered in three weekly sessions. Results from clinical trials are mixed. Some trials show meaningful benefit: one study of 114 patients found 61% had at least a 50% pain reduction at three months, compared to 29% in the placebo group. But other trials showed no difference between shockwave therapy and sham treatment. According to NICE, the evidence is inconsistent enough that shockwave therapy is generally reserved for cases that haven’t responded to other treatments after six months or more.
Building a Practical Recovery Plan
The most effective approach layers several of these strategies together. Start with eccentric exercises three times per week, use a counterforce brace during aggravating activities, and apply heat before exercise sessions. If you need pain relief, a topical anti-inflammatory gel is a sensible option with minimal side effects. Fix your workstation ergonomics so you’re not re-irritating the tendon eight hours a day.
Most cases of tennis elbow resolve within 6 to 12 months with consistent conservative care. The key word is consistent. Tendon tissue remodels slowly, and stopping your exercises once the pain starts to fade is the most common reason for relapse. Continue your strengthening program for at least a month after symptoms have fully resolved to give the tendon time to rebuild its structural integrity.
