Radial tunnel syndrome
Pain 3–5 cm distal to the epicondyle, deep ache, often worse at night. Resisted middle-finger extension reproduces pain.

When to see a doctor for tennis elbow
TL;DR. Most lateral epicondylitis (ICD-10 M77.1) resolves with progressive loading and doesn't need imaging, injection, or surgery. See a clinician if you have any red flag below, no improvement after 6 weeks of correct self-management, or symptoms beyond 6 months. Urgent care for trauma, fever, joint locking, or rapid neurological change.

Urgent — same-day care
!! Direct trauma to the elbow
Fall onto outstretched hand, blow, or fracture suspicion. Could be radial head fracture, collateral ligament tear, or dislocation — none of these are tennis elbow.
!! Fever + hot, red, swollen elbow
Possible septic joint, septic bursitis, or cellulitis. Medical emergency.
!! Visible deformity or inability to bend/straighten
Joint locking, true loss of range = mechanical block. Needs imaging now.
!! Sudden severe weakness, numbness, or paralysis
Acute nerve compromise. Rule out posterior interosseous nerve compression, cervical radiculopathy, or vascular event.
Book a GP or physio appointment (within 1–2 weeks)
- Symptoms >6 weeks despite consistent loading + activity modification.
- Night pain waking you up — atypical for routine tendinopathy.
- Numbness, tingling, or burning into the forearm, hand, or fingers — suggests nerve involvement (radial tunnel, posterior interosseous nerve, ulnar/median entrapment).
- Grip weakness severe enough to drop objects (kettle, mug, child).
- Pain not localised to the lateral epicondyle — diffuse forearm, posterior elbow, or shoulder-referred pain often points to a different diagnosis.
- Recurrent flares >3× per year despite rehab.
- Pre-existing conditions: diabetes, rheumatoid arthritis, recent oral steroids, prior tendon ruptures.
Specialist referral (orthopaedic / sports medicine)
- >6 months of symptoms despite supervised loading.
- Imaging-confirmed partial extensor tendon tear or significant tendinosis.
- Need for image-guided injection (PRP, autologous blood, hyaluronic acid).
- Discussion of surgical debridement after failed conservative care.
- Suspicion of posterolateral rotatory instability or other intra-articular pathology.
Conditions that mimic tennis elbow
Cervical referred pain (C5–C7)
Neck stiffness, dermatomal arm pain, symptoms change with head position. Examine the cervical spine.
Posterolateral rotatory instability
History of dislocation or prior cortisone injections. Catching, clicking, instability with axial load.
Osteoarthritis / loose body
Mechanical catching, loss of terminal extension, crepitus. Plain X-ray usually sufficient.
Synovitis (RA, PsA, gout)
Bilateral, prolonged morning stiffness >1 hour, systemic features. Needs rheumatology.
Partial extensor tendon tear
Acute "pop" episode + sudden weakness. Ultrasound or MRI confirms.
What to bring to your appointment
- Symptom timeline: onset, triggers, current week.
- Daily pain log (Tennis Elbow Oracle Pro exports this as a clinician PDF).
- What you've already tried: braces, exercises, NSAIDs, rest.
- Occupational and sporting load (hours/week of grip-heavy tasks).
- Specific question: "Is this still lateral epicondylitis, and what's our next step if I'm not better in 4 weeks?"

FAQ
When should I see a doctor for tennis elbow?
If pain persists beyond 6 weeks of consistent self-management, if night pain wakes you, if you have numbness or tingling into the hand, after any direct trauma, if grip weakness is severe enough to drop objects, or if the elbow is visibly swollen, hot, or locked.
Do I need an MRI for tennis elbow?
Routine cases are a clinical diagnosis — no imaging required. MRI or ultrasound is reserved for failure to improve after 3–6 months of correct loading, suspicion of a different diagnosis, or pre-surgical planning.
Are corticosteroid injections worth it?
Short-term pain relief, worse long-term outcomes. JAMA 2013: cortisone recovered fastest at 4 weeks but had significantly higher recurrence at 1 year vs placebo or physiotherapy.
When is surgery considered?
Surgical referral typically after 6–12 months of failed conservative treatment including supervised loading. Options: open or arthroscopic ECRB debridement. Recovery is 3–6 months.
Can I use the Oracle while seeing a physio?
Yes — most physios appreciate the daily traffic-light log and weekly PDF export. It removes "how were you between sessions?" from the conversation.
