Golfer’s elbow is caused by damage to the tendons that attach your forearm muscles to the bony bump on the inside of your elbow. Despite the name, most people who develop it have never picked up a golf club. Any activity that involves forceful gripping, twisting, or pulling with your hands can overload these tendons over time, leading to pain and weakness. The condition affects roughly 1% to 3% of the population each year, with the highest rates in people over 40.
What Happens Inside the Tendon
Several forearm muscles responsible for bending your wrist, rotating your forearm, and gripping with your fingers all converge into a shared tendon that anchors to the inner elbow. When you repeatedly stress that tendon with forceful hand and wrist movements, microscopic tears develop faster than your body can repair them.
Over time, this isn’t so much an inflammatory problem as a degenerative one. The tendon tissue breaks down, loses its organized structure, and becomes weaker. That’s why the pain tends to creep in gradually rather than appearing after a single event. By the time you notice it, weeks or months of accumulated damage have already occurred. This distinction matters because treatments aimed purely at reducing inflammation, like ice and anti-inflammatory drugs, only address part of the picture.
Forceful Gripping Is the Primary Trigger
Research into workplace injuries has clarified exactly which types of movement cause golfer’s elbow. Forceful work, meaning any task that requires you to grip, squeeze, or push with significant effort, nearly doubles the risk. One large occupational study found that workers exposed to forceful hand tasks were about twice as likely to develop the condition compared to those who weren’t.
Interestingly, repetitive motion alone doesn’t appear to be a significant risk factor. The National Institute for Occupational Safety and Health has concluded there’s insufficient evidence linking repetitive work by itself to golfer’s elbow. It’s the force behind the motion that matters most. This explains why the condition shows up frequently in specific industries: 65% of food industry workers and 69% of cashiers in one study reported regular exposure to the kind of forceful tasks that stress the inner elbow. Jobs that involve holding tools in position, turning and screwing, or sustained gripping are particularly problematic.
Sports That Stress the Inner Elbow
In golf, the critical moment happens just before and during contact with the ball or ground. The lead arm experiences a strong inward force at the elbow during the downswing, and that stress concentrates right where the forearm tendons attach. Hitting the ground (a “fat shot”), gripping the club too tightly, or using a club that’s too heavy all amplify the load on those tendons.
Throwing sports carry similar risks. Baseball pitchers, javelin throwers, and football quarterbacks generate intense inward stress on the elbow during the acceleration phase of a throw. Racquet sports can cause it too, particularly serves and forehands with heavy topspin. In all of these activities, poor body mechanics, improper technique, and inadequate equipment are consistent contributing factors. A golfer with a smooth, efficient swing distributes force across the whole kinetic chain. One who compensates with the wrists and forearms concentrates that force right at the vulnerable tendon attachment.
Who’s Most at Risk
Age is the clearest risk factor outside of activity type. Prevalence peaks after 40, when tendons naturally lose some of their elasticity and blood supply. Healing slows down, so the balance tips toward accumulated damage rather than recovery.
Smoking history may also play a role in tendon health, though the evidence is more established for the outer elbow (tennis elbow) than the inner. One study found that former smokers were more than twice as likely to develop tennis elbow compared to people who had never smoked. The researchers suggested that tobacco-related tendon damage accumulates over years and persists even after quitting. While this specific finding was for the outer elbow, the underlying biology of tendon degeneration is similar on both sides, and the same vascular damage that weakens one tendon likely affects the other.
How It Feels and How It’s Diagnosed
The hallmark symptom is tenderness on the inner side of your elbow, typically just below and slightly in front of the bony bump. The pain often radiates down the inner forearm. You’ll notice it most when shaking hands, turning a doorknob, picking up something with your palm facing down, or squeezing objects.
Diagnosis is straightforward and usually doesn’t require imaging. A clinician will press on the tender spot and then ask you to bend your wrist or rotate your forearm against resistance while your elbow is straight. If that reproduces your pain, the diagnosis is fairly clear. Passive stretching of the forearm, where someone else extends your wrist and rotates your forearm outward, will also provoke symptoms because it pulls on the damaged tendon. For athletes who throw, a specialized test that snaps the elbow from a bent to a straight position under inward stress can reveal whether the ligament on the inner elbow is also involved.
Why It Persists and What Helps
Golfer’s elbow tends to linger because the tendon has poor blood supply compared to muscle, and most people can’t fully rest their hands and forearms for the weeks it takes to heal. Continuing the aggravating activity, even at lower intensity, resets the damage cycle.
The most effective long-term approach involves gradually loading the tendon through specific exercises, particularly eccentric movements where the muscle lengthens under tension. This stimulates the tendon to remodel and rebuild its structure. A typical rehab program takes 6 to 12 weeks of consistent work before meaningful improvement.
Injection therapies offer different tradeoffs. Corticosteroid injections provide rapid pain relief, peaking around 6 to 8 weeks, but symptoms frequently return afterward. Imaging studies have shown that corticosteroids can actually thin the tendon and contribute to tissue erosion over time. Platelet-rich plasma injections work more slowly but show ongoing improvements out to one and even two years. PRP-treated tendons also tend to thicken rather than thin, with fewer signs of tendon tearing on follow-up imaging. The trade-off is patience: PRP requires weeks before you notice a difference, while a corticosteroid shot can bring relief within days.
For most people, the practical takeaway is that golfer’s elbow isn’t caused by a single event or a sudden injury. It’s the result of cumulative tendon overload, driven by how much force your hands and wrists absorb during daily or athletic activities, and shaped by age, technique, and the tools you use. Addressing the root cause, whether that’s grip strength, swing mechanics, or workplace ergonomics, matters more than any single treatment.
