A tennis elbow rarely has anything to do with tennis. Around 95% of those affected have never played the sport. Much more often, the irritation is caused by work-related or everyday overuse of the forearm muscles – common in tradespeople, hairdressers, office workers, or anyone doing intensive computer work. Medically, it’s known as lateral epicondylitis – a painful inflammation at the tendon insertion of the forearm extensor muscles on the outer elbow.
Cause and progression
The inflammation results from sustained misuse or overuse – often triggered by repetitive hand movements or excessive force. High-risk groups include those with physically demanding jobs or intensive computer use. Symptoms usually develop gradually and worsen under strain.
Symptoms
- localized pressure pain on the outer elbow
- pain when extending or lifting the wrist
- radiating pain into the forearm or hand
- reduced grip strength
Diagnosis
Diagnosis is typically clinical – based on targeted movement tests and palpation. Imaging (e.g., ultrasound) is only needed in rare cases to rule out other conditions.
Common Synonyms
- tennis elbow
- tennis arm
- lateral epicondylitis
- mouse arm / mouse elbow
Treatment
Osteopathic and physiotherapeutic treatment can relieve irritation at the tendon attachment and release muscle tension. Acupuncture is also used as a complementary approach. With targeted therapy, the affected arm is often functional again after a short time.
