Tennis elbow — clinically known as lateral epicondylalgia or lateral epicondylitis — is one of the most common overuse injuries in the upper extremity. And here's the twist: fewer than 5% of the tennis elbow patients I see actually play tennis. Most are office workers, tradespeople, mechanics, hairstylists, chefs, and gym-goers whose forearms are getting overworked in ways they don't fully realize.
What's actually going on
The pain of tennis elbow comes from the common extensor tendon — the tendon where your wrist and finger extensor muscles all attach to a small bony prominence on the outside of your elbow (the lateral epicondyle). When these muscles are used repetitively or forcefully, tiny microtears develop in the tendon. Instead of healing normally, the tendon enters a state of chronic tendinopathy — degenerative changes that don't respond to typical anti-inflammatory approaches.
This is why the older term "epicondylitis" is falling out of favour. There's actually very little classic inflammation in most cases. What we're really dealing with is a degenerative tendinopathy — a failure of the tendon to heal properly under repeated load.
Common activities that overload this tendon:
- Sustained gripping (tools, steering wheel, phone, computer mouse)
- Repetitive wrist extension (typing, painting, cooking)
- Heavy lifting with a pronated grip (deadlifts, rows, chin-ups)
- Sudden increases in activity — a new project at work, a weekend of yard work, an aggressive new gym program
- And yes, backhand tennis strokes (in the small minority who actually play)
What tennis elbow feels like
- Sharp or aching pain on the outside of the elbow, sometimes radiating down the forearm
- Tenderness right at the bony point when pressed
- Weakness in grip strength — you can't open a jar, hold a coffee cup, or shake hands without pain
- Pain provoked by wrist extension against resistance
- Symptoms often worse in the morning and after activity
The condition can be surprisingly persistent. Without proper treatment, tennis elbow often drags on for months or years, gradually worsening if the underlying loading pattern isn't addressed.
Why rest alone doesn't fix it
The instinct with any painful condition is to rest. And rest does help acute flares. But complete rest for chronic tendinopathy actually delays recovery — the tendon needs progressive load to remodel and heal. This is one of the most important shifts in our understanding of tendinopathy in the last two decades: load, done correctly, is the medicine.
Patients who "rest and wait" often find that as soon as they resume normal activity, the pain returns immediately — because the tendon hasn't been rebuilt, just quieted.
How we treat tennis elbow at The Way Chiro
The most effective plans combine hands-on care with progressive loading, plus addressing the upstream factors that overload the tendon in the first place.
Soft tissue therapy. Graston Technique and ART on the common extensor tendon, wrist extensors, and forearm musculature are cornerstone interventions. Dry needling for stubborn trigger points in the extensor carpi radialis brevis (the primary culprit) can produce rapid relief.
Shockwave therapy has strong evidence for chronic lateral epicondylalgia. It stimulates the local healing response in tissue that has stalled in a degenerative pattern.
Joint mobilization of the elbow, wrist, and often the cervical spine addresses restrictions that contribute to abnormal loading.
Progressive tendon loading — this is the piece that makes recovery durable. Isometric holds early, transitioning to slow eccentric wrist extensions with light weight, then heavier loading over weeks. This isn't glamorous work, but done consistently it rebuilds the tendon.
Acupuncture can help modulate the chronic pain sensitivity that often accompanies long-standing tendinopathies.
Ergonomic and grip modification. If your mouse, workstation, or grip pattern is driving the overload, no amount of treatment will hold without addressing it. Sometimes a simple change like using a vertical mouse or switching to double-overhand deadlifts is game-changing.
What you can do today
- Isometric wrist extension. Hold your affected arm out with wrist neutral, gently press the back of the hand against a fixed surface (like a wall or the underside of a table). Hold 30-45 seconds. 3-5 reps, daily. Isometrics are excellent early tendon rehab and often reduce pain immediately.
- Modify aggravating activities. If gripping the phone or mouse hurts, use a headset and switch to a vertical or trackball mouse.
- Warm up the forearm before gripping tasks. Wrist circles, gentle stretching of the extensors (arm forward, palm down, gently pull hand toward you).
- Avoid steroid injections as a first-line treatment. They can provide short-term relief but consistently worsen long-term outcomes for tendinopathy.
The recovery timeline
Acute tennis elbow caught early often resolves within 6-8 weeks. Chronic cases — those that have been brewing for months or years — typically require 3-6 months of consistent care, but they still resolve when addressed properly. The patients who struggle are usually those who never load the tendon appropriately or who keep grinding through the aggravating activity without modification.
If your elbow has been bothering you for more than a few weeks, get assessed. Tennis elbow is highly treatable when we address the whole picture — not just the sore spot.
