Red Flags - When Physiotherapy Is Not the Right Answer
A good physiotherapist's first job on every new patient is screening for red flags - symptoms that suggest the problem isn't musculoskeletal and needs a doctor's review before rehab begins.
Getting this right is what separates safe practice from dangerous practice. Here are the categories we screen for at every first visit.
Spine-specific red flags
- Saddle numbness - numbness in the area that would sit on a bicycle seat. Possible cauda equina syndrome. A&E immediately.
- New bladder or bowel control changes - same urgency.
- Progressive leg weakness - especially bilateral.
- Night pain that wakes you up regardless of position.
- Unexplained weight loss with new back pain.
- Fever with back pain, especially in immunocompromised or IV-drug-using patients.
Neurological red flags
- Sudden-onset facial weakness with arm or leg weakness - suspect stroke, A&E.
- Sudden severe headache unlike any before - A&E.
- Double vision, slurred speech, facial numbness with any other neurological symptom.
Vascular / cardiac red flags
- Calf pain with swelling or warmth, especially after immobility - possible DVT.
- Chest pain with shoulder or jaw pain - cardiac until proven otherwise.
- Cold, pale, pulseless limb - vascular emergency.
Musculoskeletal red flags
- Bone pain that doesn't change with position - think fracture, stress reaction, or rarely malignancy.
- Inflammatory pattern - pain and stiffness worse in the morning, with multiple symmetrical joints involved - think rheumatology.
- Suspected septic joint - red, hot, swollen, fever - urgent medical review.
What we actually do
If any of these flags show at our first visit, we don't start rehab.
We tell you plainly, we refer you to the right pathway (A&E, GP, specialist), and we document the referral.
Starting rehab on an undiagnosed red-flag presentation is how people end up in trouble. We'd rather lose a first visit than miss a serious diagnosis.
How to start
WhatsApp us your symptoms.
We'll tell you whether to come to us, see a doctor first, or go to A&E.
Asking costs nothing.
