Tennis elbow (lateral epicondylitis) affects the outer elbow, while golfer’s elbow (medial epicondylitis) affects the inner elbow. Both are common overuse tendinopathies caused by repetitive forearm movements, not just sports. Cortisone injections provide effective pain relief and reduce inflammation, while PRP injections promote tendon healing and may offer longer-term benefits in selected patients.
What is Tennis Elbow?
Tennis elbow — medically known as lateral epicondylitis or lateral epicondylalgia — is a painful condition affecting the outer side of the elbow. It involves degeneration of the common extensor tendon, which attaches to the bony prominence on the outer elbow (the lateral epicondyle).
Despite the name, most cases of tennis elbow are not caused by tennis. It is very common in people who perform repetitive forearm and wrist movements — including computer workers, painters, plumbers, and musicians.
What is Golfer's Elbow?
Golfer’s elbow — medically known as medial epicondylitis or medial epicondylalgia — is the mirror image of tennis elbow. It affects the inner side of the elbow, specifically the common flexor tendon that attaches to the medial epicondyle.
Like tennis elbow, it is not exclusive to golfers. It is common in people who perform repeated gripping, forearm rotation, or wrist flexion — including golfers, climbers, manual workers, and those who regularly carry heavy bags.
Key differences between Tennis Elbow and Golfer's Elbow
| Tennis elbow | Golfer’s elbow |
Location | Outer elbow (lateral) | Inner elbow (medial) |
Tendon affected | Common extensor tendon | Common flexor tendon |
Pain worsened by | Gripping, wrist extension | Gripping, wrist flexion |
Common activities | Computer use, tennis, painting | Golf, climbing, carrying |
Medical term | Lateral epicondylalgia | Medial epicondylalgia |
Treatment for Tennis and Golfer's Elbow
Cortisone injection
A cortisone shot for Tennis Elbow may be considered. At Alton Pain Clinic, we perform this injection under ultrasound guidance to ensure precise targeting of the affected tendon.
PRP Injection
For persistent cases — particularly those lasting more than three months — PRP (platelet-rich plasma) injection is one of the most effective interventions. PRP delivers concentrated growth factors directly into the degenerate tendon under ultrasound guidance, stimulating healing.
Book Your Appointment For Cortisone Shots or PRP Injection
At Alton Pain Clinic, we provide comprehensive, evidence-based treatment for both tennis elbow and golfer’s elbow. Our personalized approach includes conservative care, cortisone injections for effective pain relief, and PRP therapy when appropriate to promote long-term tendon healing—helping you return to your daily activities with less pain and improved function.

Frequently Asked Questions
How do I know if I have tennis elbow or golfer's elbow?
The key differentiator is the location of pain. Tennis elbow is felt on the outer side of the elbow, worsened by gripping and wrist extension. Golfer’s elbow is felt on the inner side, worsened by gripping and wrist flexion. Your consultant can confirm the diagnosis on examination and with ultrasound.
How long does tennis elbow or golfer's elbow take to heal?
Both conditions can take 6–18 months to fully resolve without treatment. With appropriate injection therapy, most patients see significant improvement within three to six months. The key is addressing the root cause — usually a combination of overuse and muscle weakness — rather than just managing symptoms.
Can I continue working or playing sport with tennis or golfer's elbow?
In many cases, yes — though activity modification may be needed. Continuing to load the tendon through pain without addressing the underlying problem is likely to prolong recovery.
