Tennis Elbow vs Golfer Elbow: Telling Them Apart

Elbow pain is one of the most common complaints we see at Rehoboth Physio & Wellness, and two conditions often get confused: tennis elbow and golfer's elbow. Despite their names, you do not need to play either sport to develop them. Both are forms of tendinopathy, meaning they involve irritation and degeneration of the tendons that attach the forearm muscles to the bony bumps of the elbow.

The key difference is location. Tennis elbow affects the outer (lateral) part of the elbow, while golfer's elbow affects the inner (medial) part. Understanding which one you have matters, because the muscles involved, the aggravating activities, and the targeted treatment differ. This guide explains how to tell them apart and when to seek a professional assessment.

What Is Tennis Elbow?

Tennis elbow, known clinically as lateral epicondylitis or lateral epicondylalgia, involves the tendons of the wrist extensor muscles, particularly the extensor carpi radialis brevis. These tendons attach to the lateral epicondyle, the bony point on the outer side of the elbow. When these tendons are overloaded, they develop microscopic tears and become painful and weak.

It is typically caused by repetitive gripping, lifting, or wrist extension. Common culprits include typing, using tools, painting, gardening, and yes, racquet sports. The pain is felt on the outer elbow and often radiates down the back of the forearm.

What Is Golfer's Elbow?

Golfer's elbow, or medial epicondylitis, affects the wrist flexor and forearm pronator tendons that attach to the medial epicondyle, the bony point on the inner side of the elbow. Like tennis elbow, it is an overuse tendinopathy rather than true inflammation in most chronic cases.

Activities involving repeated wrist flexion, gripping, or forearm rotation tend to provoke it. Think carrying heavy bags, swinging a golf club, throwing, or repetitive manual work. Pain is located on the inner elbow and can travel down into the forearm toward the wrist.

How to Tell Them Apart

The simplest way to distinguish the two is by where the pain sits and what movements make it worse. A few clear differences can help you identify which condition you may be dealing with.

• Location of pain: tennis elbow hurts on the outer elbow, golfer's elbow hurts on the inner elbow.
• Aggravating movement: tennis elbow worsens with wrist extension (bending the wrist back), golfer's elbow worsens with wrist flexion (bending the wrist forward).
• Gripping: both can hurt when gripping, but tennis elbow pain often spikes when lifting with the palm facing down.
• Tenderness: pressing on the lateral epicondyle suggests tennis elbow, while tenderness over the medial epicondyle suggests golfer's elbow.
• Referred sensations: golfer's elbow can occasionally cause tingling into the ring and little fingers if the nearby ulnar nerve is irritated.

Why the Distinction Matters

Although both conditions share a similar underlying process, the muscles and tendons involved are different, so the strengthening exercises and load management strategies are tailored to each. Treating golfer's elbow with exercises designed for tennis elbow, or the reverse, can slow recovery or worsen symptoms.

There are also conditions that can mimic these problems. Inner elbow pain can sometimes stem from ulnar nerve irritation (cubital tunnel syndrome), and outer elbow symptoms can occasionally relate to the radial nerve or referred pain from the neck. A proper assessment rules these out so you are treating the right problem.

Common Symptoms to Watch For

Both conditions tend to develop gradually rather than from a single injury. Early on you may notice a dull ache that eases with rest, but over time it can become persistent and interfere with daily tasks such as opening jars, shaking hands, turning a key, or carrying shopping.

You may also feel weakness in your grip, stiffness in the morning, and tenderness when you press directly on the affected bony point. Symptoms that last more than a few weeks, or that are getting worse, are a strong signal to seek professional advice rather than waiting it out.

How These Conditions Are Treated

The cornerstone of treatment for both tennis and golfer's elbow is progressive loading, a structured programme of strengthening exercises (often including eccentric and isometric work) that gradually rebuilds tendon capacity. This is supported by activity modification to reduce the overload that caused the problem in the first place.

Additional approaches may include manual therapy, soft tissue release, bracing, taping, and advice on ergonomics or technique. Most cases improve well with conservative physiotherapy and do not require injections or surgery. Patience is important, because tendons respond to load over weeks and months rather than days.

If you are unsure whether you have tennis elbow, golfer's elbow, or something else entirely, a physiotherapy assessment at Rehoboth Physio & Wellness in Grand Cayman can give you clarity. Our therapists will examine your elbow, identify the exact source of your pain, rule out nerve or referred causes, and build a personalised treatment plan to get you back to the activities you enjoy without ongoing discomfort.
