Tennis Elbow vs Other Elbow Pain
TL;DR. Outer-elbow pain has several causes that mimic tennis elbow. Getting the diagnosis right matters: the wrong rehab program for the wrong condition wastes months. This guide covers the most common mimics: radial tunnel syndrome, golfer's elbow, cubital tunnel, bursitis, and cervical referred pain.
Educational only. Not medical advice. A qualified clinician must confirm any diagnosis — especially before starting a rehabilitation program.
Quick comparison table
| Condition | Pain location | Key distinguishing feature | Neurological symptoms |
|---|---|---|---|
| Tennis elbow (lateral epicondylitis) | Outer elbow — lateral epicondyle | Tenderness AT the epicondyle; worsens with resisted wrist extension | None |
| Radial tunnel syndrome | Outer forearm — 4–5 cm below epicondyle | Tenderness distal to epicondyle; worsens with resisted supination / middle-finger extension | Possible aching, sometimes forearm weakness |
| Golfer's elbow (medial epicondylitis) | Inner elbow — medial epicondyle | Tenderness ON the inner elbow; worsens with resisted wrist flexion | Sometimes ulnar-nerve stretch symptoms |
| Cubital tunnel syndrome | Inner elbow + hand | Tingling/numbness in ring and little finger (ulnar nerve) | Yes — ring & little finger |
| Olecranon bursitis | Back of elbow tip | Visible swelling at the elbow tip; fluctuant mass; no wrist/grip pain | None |
| Posterior interosseous nerve (PIN) entrapment | Outer forearm | Wrist and finger drop weakness without sensory loss | Motor only |
| C6 cervical radiculopathy | Neck → outer elbow → thumb | Neck pain; symptoms change with head position; Spurling's test positive | Thumb/index finger numbness |
| Elbow OA / loose body | Deep inside elbow | Reduced range of motion; locking; crepitus on movement | None typically |
Detailed comparisons
Tennis elbow vs Radial tunnel syndrome
These are frequently confused — some sources suggest up to 5% of patients diagnosed with tennis elbow actually have radial tunnel syndrome, and both can coexist.
- Location: Tennis elbow → lateral epicondyle. Radial tunnel → 4–5 cm below and in front of the epicondyle, over the radial head (where the radial nerve passes through the supinator muscle).
- Provocative test: Tennis elbow → resisted wrist extension. Radial tunnel → resisted forearm supination (palm turn from down to up) AND resisted extension of the middle finger with the elbow extended.
- Night aching: More common in radial tunnel syndrome.
- Treatment divergence: Radial tunnel may need neural mobilisation and nerve decompression if conservative management fails. Tennis elbow loading exercises may aggravate radial tunnel.
Tennis elbow vs Golfer's elbow (medial epicondylitis)
Different sides of the elbow, same protocol family. Easy to distinguish by location.
- Location: Tennis elbow → outside (lateral). Golfer's elbow → inside (medial).
- Provocative test: Tennis elbow → resisted wrist extension (palm down). Golfer's elbow → resisted wrist flexion (palm up).
- Sport triggers: Tennis elbow → backhand, padel, mouse. Golfer's elbow → golf swing, forehand, throwing, hammering.
- Prevalence: Tennis elbow is 7–10× more common.
Tennis elbow vs Cubital tunnel syndrome
Easy to separate if you check for neurological symptoms. Tennis elbow has none.
- Location: Cubital tunnel → medial elbow (inner side), where the ulnar nerve passes behind the medial epicondyle.
- Key symptom: Tingling or numbness in the ring finger and little finger — this does not occur with tennis elbow. Often worse when the elbow is bent (e.g. holding a phone).
- Tinel's sign: Tapping behind the medial epicondyle reproduces tingling into the ring and little finger.
- Treatment: Cubital tunnel responds to nerve mobilisation, activity modification, and elbow padding at night. Severe cases require surgical decompression. Loading exercises for tennis elbow are irrelevant.
Tennis elbow vs Cervical radiculopathy (C6)
C6 radiculopathy (nerve root compression in the neck) is the most important mimic to rule out. Starting a loading program for lateral elbow pain that is actually referred from the neck will not help — and may worsen symptoms.
- Pattern: C6 refers pain from the neck down the outer arm, through the elbow, to the thumb and index finger.
- Clues for cervical origin: Neck pain or stiffness, symptoms that change with neck position (looking up or rotating the head), pain that runs from neck to elbow rather than starting at the elbow, thumb or index finger numbness.
- Spurling's test: A clinician extends and rotates your head toward the affected side while applying axial compression — reproduces arm pain if C6 is involved. Negative in pure tennis elbow.
Tennis elbow vs Olecranon bursitis
Easy to distinguish visually — bursitis produces a visible soft lump at the tip (back) of the elbow.
- Location: Olecranon bursitis = tip of the elbow (posterior, over the olecranon). No wrist extension pain, no grip weakness.
- Appearance: Fluctuant (fluid-filled) swelling at the elbow tip. Can be warm and red if infected (septic bursitis — requires antibiotics/aspiration).
- Cause: Leaning on hard surfaces, direct trauma, gout, rheumatoid arthritis.
Red flags — always see a clinician
Frequently asked questions
How do I know if it's tennis elbow or radial tunnel syndrome?
Tenderness at the lateral epicondyle = tennis elbow. Tenderness 4–5 cm below, over the radial head = radial tunnel. Radial tunnel worsens with resisted forearm supination and middle-finger extension. Both can coexist. A clinician differentiates with targeted tests.
What is the difference between tennis elbow and cubital tunnel syndrome?
Tennis elbow: outer elbow pain, no neurological symptoms. Cubital tunnel: inner elbow, tingling in ring and little finger (ulnar nerve). If you have hand tingling, see a clinician — different management, may need surgical decompression.
How do I tell tennis elbow from golfer's elbow?
Press the outer bony bump (lateral epicondyle) = tennis elbow. Press the inner bony bump (medial epicondyle) = golfer's elbow. Resisted wrist extension (palm down) → outer pain = tennis elbow. Resisted wrist flexion (palm up) → inner pain = golfer's elbow.
Could my elbow pain be from my neck?
Yes. C6 cervical radiculopathy refers pain to the lateral elbow and thumb/index finger. Clues: neck stiffness, symptoms change with neck position, pain runs from neck down. A clinician differentiates with Spurling's test.
