Neither condition needs you to play the sport it's named after. Most people who get "tennis elbow" have never picked up a racquet — they've been at a keyboard, gripping tools, or lifting the same way for months. The names are misleading; the mechanism is what actually matters.

Same joint, opposite sides

Both conditions involve overuse of the tendons around the elbow, but on opposite sides of the joint. Tennis elbow affects the outside of the elbow, from repetitive gripping and wrist extension — the motion of pulling a mouse back, using a screwdriver, or carrying a bag by the handle for a long day. Golfer's elbow affects the inside, from repetitive wrist flexion — the motion of gripping a golf club, or repeated lifting with a bent wrist.

How to tell which one you have

The simplest clue is where it hurts. Press along the bony bump on the outside of your elbow — pain there, especially when you try to extend your wrist against resistance, points to tennis elbow. Press the inside bony bump instead, and pain when you flex your wrist against resistance points to golfer's elbow. Both often worsen with gripping.

The good news: both usually settle with the right approach

Most cases improve with conservative treatment — no injections, no surgery. What actually helps:

• Activity modification — not stopping everything, but adjusting grip technique, tool handles, or workstation setup to reduce the repetitive strain
• Manual therapy — hands-on work to reduce tension in the forearm muscles feeding into the tendon
• Progressive strengthening — the tendon needs loaded exercise to heal properly, not just rest
• Taping or bracing — to offload the tendon during activities that provoke it

When shockwave therapy comes in

Shockwave therapy isn't a first-line treatment for either condition — it's reserved for chronic or stubborn cases that haven't responded to a proper course of structured rehabilitation. Jumping straight to it before trying the basics usually isn't necessary.

Why it comes back if you ignore the cause

Both conditions are classic overuse injuries, which means the tendon will keep getting irritated if the underlying movement pattern doesn't change. Treating the pain without addressing your grip, your desk setup, or your lifting technique is why so many people get short-term relief and then a repeat episode months later.
