Golfer’s elbow and tennis elbow are not the same condition. They affect opposite sides of the elbow, involve different sets of muscles and tendons, and produce pain in different locations. But they share the same underlying mechanism: repetitive overuse that gradually damages the tendons connecting forearm muscles to the bony bumps on either side of your elbow joint.
Because the two conditions overlap in cause, symptoms, and treatment, they’re easy to confuse. Here’s how to tell them apart and what to do about either one.
Where the Pain Shows Up
The quickest way to distinguish the two is by touching your elbow. Tennis elbow causes pain on the outer (lateral) side of the elbow. It typically starts as a dull ache that extends down the top of the forearm and worsens when you grip objects, shake hands, or lift something with your palm facing down.
Golfer’s elbow causes pain on the inner (medial) side of the elbow, and it tends to radiate down the inside of the forearm toward the wrist. It becomes sharper with gripping and twisting motions, like turning a doorknob or squeezing a handle.
Different Tendons, Same Type of Injury
Your elbow has two bony bumps, one on each side. Each bump serves as an anchor point for a group of forearm tendons. Tennis elbow damages the tendons that extend your wrist (pull it backward), which attach to the outer bump. The muscle most commonly injured is the one that stabilizes your wrist during gripping. Golfer’s elbow damages the tendons that flex your wrist (curl it forward) and rotate your forearm palm-down, which attach to the inner bump.
In both cases, the injury isn’t a sudden tear. It’s a gradual breakdown of the tendon fibers from repetitive stress, which is why doctors classify both as overuse injuries rather than inflammatory conditions. Chronic cases show degenerated tendon tissue rather than the active inflammation most people assume is causing the pain.
You Don’t Need to Play Golf or Tennis
Despite the names, most people who develop these conditions aren’t athletes. Tennis elbow is common among computer users, manufacturing workers, construction workers, healthcare workers, and people in the service industry. Research has flagged high-risk occupations ranging from neurosurgeons to fruit-tree farmers to coalminers to nursery cooks. Any job that involves repetitive gripping, wrist extension, or forearm rotation can cause either condition.
Tennis elbow is roughly three times more common than golfer’s elbow. Population studies put the prevalence of tennis elbow at about 1.3% of adults and golfer’s elbow at about 0.4%. Both conditions peak between the ages of 30 and 64.
How Each One Is Diagnosed
A doctor can usually diagnose either condition through a physical exam without imaging. For golfer’s elbow, the key test involves resisting wrist flexion and forearm rotation while the elbow is bent at 90 degrees. Pain on the inner elbow during forearm rotation is the most sensitive finding. For tennis elbow, the equivalent test involves resisting wrist extension, which reproduces pain on the outer elbow.
If your symptoms don’t clearly match one condition, or if your doctor suspects a ligament issue, imaging or additional tests can help rule out other problems. Inner elbow pain in particular can sometimes overlap with ulnar collateral ligament injuries, so your doctor may check ligament stability as part of the exam.
Treatment Is Nearly Identical
The good news is that both conditions respond to the same basic approach. Most people recover with rest, over-the-counter pain relievers, ice, and targeted exercises. The most effective strategy is progressive loading: gradually strengthening the affected tendons with specific resistance exercises. This stimulates the tendon to repair and remodel rather than simply waiting for pain to fade.
Recovery typically takes about six months, though it can range from a few months to 18 months depending on severity and how consistently you follow a rehab program. Returning to activity too soon is one of the most common reasons people stall or relapse.
When you’re ready to return to the activity that caused the problem, reviewing your technique matters. A golf or tennis instructor can identify swing mechanics that overload the elbow, and ergonomic adjustments at a workstation can reduce strain from typing or repetitive hand work.
Counterforce Braces
A counterforce brace is a strap worn on the upper forearm, just below the elbow, that applies targeted compression to reduce the load on the damaged tendon. The placement depends on which condition you have. For tennis elbow, the compression pad sits over the muscles on the outer forearm. For golfer’s elbow, it shifts to the inner forearm. Positioning it correctly is what makes it effective, so getting the right placement for your specific condition matters more than the brand of brace.
When Conservative Treatment Isn’t Enough
For chronic cases that don’t improve after several months of rehab, injection therapy is an option. Corticosteroid injections provide faster short-term relief, with significantly better pain scores at four and eight weeks compared to platelet-rich plasma (PRP) injections. But the picture reverses over time. A 2025 randomized trial found that by six months, PRP-treated patients had better outcomes, and the advantage held at one year. Grip strength was higher and pain scores were lower in the PRP group across the full study period.
The reason for the flip likely comes down to biology. Corticosteroids are powerful anti-inflammatory agents, but chronic tendon injuries aren’t primarily inflammatory. Studies have shown that corticosteroid injections can actually accelerate tendon degeneration, destroy collagen, and increase the risk of tendon rupture. PRP, which uses concentrated growth factors from your own blood, appears to support genuine tendon healing rather than just masking symptoms.
Surgery is rarely needed. It’s reserved for cases that fail to respond to six to twelve months of conservative treatment, and most people never reach that point.
Can You Have Both at Once?
Yes. Because both conditions stem from repetitive forearm use, people whose work or hobbies involve heavy gripping and wrist movement can develop pain on both sides of the elbow simultaneously. The treatment approach remains the same: rest, progressive strengthening exercises targeting both muscle groups, and bracing as needed. If you’re experiencing pain on both sides, it’s worth having both areas evaluated to confirm you’re not dealing with a different elbow problem that mimics one of these conditions.
