When to See a Doctor — red flags and when physiotherapy is not the first step
Most musculoskeletal pain responds well to physiotherapy. But some situations need a medical evaluation — before treatment, alongside it, or instead of it. A clinic that respects its own limits is a safer clinic for you. This page sets out exactly where the line runs, and how we handle a referral when it is needed.
Physiotherapy is the proven treatment for most musculoskeletal problems, but some signs mean you need a doctor first: progressive neurological signs, suspected fracture after trauma, fever with pain, unexplained weight loss, new pain with a cancer history, sudden calf swelling (DVT), or post-surgical complications. Recovery TLV screens for these and refers you out when they are present.
Private physiotherapy in Israel does not replace medical assessment — it complements it. As a physiotherapist licensed by the Ministry of Health, I can assess musculoskeletal conditions, build a treatment plan, and track progress. But some situations require a medical diagnosis first — or a physician working in parallel. This page is full transparency about where that boundary sits, and how I manage the referral when one is needed.
What are red flags?
Red flags are findings in your history or physical examination that raise suspicion of serious pathology requiring medical evaluation — not just musculoskeletal treatment. A red flag does not mean a definite diagnosis. It means "this needs to be checked" before, or alongside, physiotherapy.
The term comes from the clinical screening literature (Henschke et al., Arthritis & Rheumatism 2009; Downie et al., BMJ 2013; Finucane et al., JOSPT 2020). Licensed physiotherapists are specifically trained to screen for these signs at the first encounter and to keep screening during a course of treatment. Most of the time the answers are routine and reassuring — but the screen has to happen in every case. Identifying a red flag prompts an evaluation; it is not, by itself, a diagnosis.
Universal urgent red flags
Before you book a physiotherapy appointment — if you have one of these signs, go first to an emergency department, urgent care, or a specialist physician. Physiotherapy is not the appropriate first-line treatment for any of these.
Needs immediate medical evaluation
Systemic or neurological warning signs that cannot be managed through physiotherapy alone.
- Loss of bladder or bowel control — suspected cauda equina syndrome. Emergency department immediately.
- Saddle anaesthesia (numbness around the perineum or inner thighs) — suspected cauda equina syndrome.
- Progressive leg weakness worsening over days — suspected urgent neurological condition.
- Fever with severe pain or systemic features — suspected infection.
- Unexplained weight loss with persistent pain — needs medical evaluation.
- Cancer history with new pain — evaluation required before physiotherapy.
- Significant trauma or suspected fracture — imaging first.
- Hot, red, swollen calf, warm to the touch — suspected DVT (deep vein thrombosis).
- Chest pain, shortness of breath, or cardiovascular signs — emergency department immediately.
- Severe night pain unrelated to movement or posture — needs medical work-up.
- After surgery: fever, wound discharge, spreading redness, local heat — suspected infection.
What to do: Contact an urgent medical service, the emergency department, or urgent primary care. Do not wait for a physiotherapy appointment. Once the initial medical care is done, we can talk about appropriate rehabilitation.
For two of the most common scenarios, validated decision rules tell clinicians when imaging is warranted. They are useful as a plain sign-to-action guide:
| Warning sign | What it may indicate | Action |
|---|---|---|
| Saddle numbness · bladder/bowel changes · progressive leg weakness | Cauda equina syndrome | Emergency department — same hour |
| Inability to bear weight after trauma · suspected fracture | Fracture (Ottawa Knee / Ankle Rules apply) | Orthopaedist + imaging before loading |
| Fever · night pain · recent infection | Spinal or joint infection | Family physician / specialist — promptly |
| Unilateral hot, swollen, painful calf | Deep vein thrombosis (DVT) | Urgent medical assessment — do not massage or mobilise |
| Post-operative fever · wound discharge · sudden loss of function | Post-surgical complication | Back to the operating surgeon |
Region-specific red flags
Signs that appear in the context of pain in a particular area and suggest the problem is not purely musculoskeletal. In these cases we refer you to a physician before starting physiotherapy, or recommend treating in parallel.
Low back & sciatica
- Progressive weakness in one or both legs, not just momentary giving-way
- Bilateral numbness or numbness in the saddle area
- Loss of bladder or bowel control
- Non-mechanical pain (does not change with position)
- Significant trauma (accident, fall from height)
- Osteoporosis history with sharp local pain
Neck & head
- Bilateral weakness in the arms or legs (suspected myelopathy)
- Unexplained gait disturbance after neck pain
- A "new and different" headache — not your familiar pattern
- Dizziness with vomiting or visual disturbance
- Neck trauma (road accident, fall) — fracture must be ruled out
- Systemic features (fever, weight loss) with neck pain
Shoulder
- Recent dislocation or subluxation — needs orthopaedic work-up
- Sudden loss of power after trauma (suspected full rotator-cuff tear)
- Neurological signs radiating down the arm
- Non-mechanical pain (unrelated to position or movement)
- Fever, redness, swelling (suspected infection or systemic inflammation)
Knee
- Inability to bear weight after trauma
- Rapid swelling within two to three hours of injury (haemarthrosis)
- True locking — not just a feeling of catching
- Severe instability after injury (a sense of "giving way")
- Suspected fracture (Ottawa Knee Rules: age 55+, patellar tenderness, inability to flex to 90°, inability to take four steps)
Ankle & lower leg
- Sudden hot, red, swollen calf — suspected DVT
- Inability to bear weight after trauma (Ottawa Ankle Rules)
- Persistent numbness or weakness in parts of the foot
- Colour change beyond ordinary swelling
- Severe pain with systemic fever
Post-surgical rehabilitation
- Fever above 38° — suspected wound or systemic infection
- Wound discharge, spreading redness, local heat
- Sudden loss of a function that was previously intact
- Marked asymmetric calf swelling — suspected DVT (common after limb surgery)
- Unexpected worsening of pain (sudden, beyond the "expected pain" of rehab)
- Any deviation from the protocol set by Alejandro or the surgeon

What Recovery TLV does not treat
Recovery TLV focuses on musculoskeletal, sports, and post-surgical physiotherapy. The following are outside our scope — we will point you to the appropriate type of practitioner:
An honest statement: this is not a list of negatives — it is a list of where we are not the right experts. A physiotherapist who treats "everything" probably does everything averagely. We would rather be excellent within a defined scope.
When Recovery TLV refers out
When I identify that a case needs medical evaluation — before, alongside, or instead of physiotherapy — this is how I handle it:
-
Identification during screening. At the initial assessment or during a course of treatment, if red flags appear we stop and revisit the clinical history. The decision is not automatic: it is based on the combination of the signs, the medical history, and the clinical presentation.
-
A clear conversation with you. If I think you need a physician, I tell you directly, explain which sign is concerning and why, and which type of doctor is recommended (family physician, orthopaedist, neurologist, emergency department). No drama, no glossing over.
-
A written summary of findings when needed. If you want to take a summary of what I found on clinical examination to your doctor, I can prepare one (a description of the findings, the tests I performed, what concerns me, what I suggest evaluating). It is not a formal medical document — it is a physiotherapy summary that shortens the medical consultation.
-
Coordination with the treating physician. If you are already followed by an orthopaedist, surgeon, or other specialist and there is a conflict between their recommendation and what I propose, we talk it through. When in doubt, the medical recommendation takes precedence and I adapt the physiotherapy plan accordingly.
-
Back to physiotherapy — when it is the right step. Once the physician has evaluated and confirmed that physiotherapy is the next step (or that we should treat in parallel), we pick up where we left off. Throughout, how we measure and track progress stays the same — objective, criteria-based outcomes you can see on paper.
An important note: I do not maintain a formal network of referring physicians — this is a single-clinician clinic. My recommendations are for a direction (a type of doctor / a field), not a specific person. You choose the specific physician through your Kupah or insurance.
Why this matters
Clinics that treat "everything" — without recognising when a problem is out of scope — put patients at risk. The clinical literature is consistent: screening for red flags at the first encounter is part of the clinical standard (Henschke et al., Arthritis & Rheumatism 2009; Downie et al., BMJ 2013). Licensed physiotherapists are specifically trained to screen for conditions that require referral.
In practice this means: before I assess your knee, I ask about a cancer history. Before I touch your back, I check whether you have lost bladder or bowel control. Before I prescribe shoulder exercises, I ask when the last trauma was. Most of the time the answers are routine — and that is fine. But the screen has to happen in every case.
A personal statement: I would rather lose a potential patient who never needed to reach me than lose an active patient to a delayed medical diagnosis. That is the approach I would expect from a clinic I would choose for my own family.
Red-flag categorisation on this page follows the International Framework for Red Flags for Potential Serious Spinal Pathologies (Finucane et al., JOSPT 2020) and the spinal red-flag screening evidence (Henschke et al., Arthritis Rheum 2009; Downie et al., BMJ 2013). Knee and ankle imaging decisions reference the validated Ottawa Knee and Ottawa Ankle Rules (Stiell et al., JAMA 1996 and 1994).

WHAT THIS PAGE COVERS — Red flags (clinical warning signs) that indicate a patient with musculoskeletal complaints should be evaluated by a physician before or alongside physiotherapy. Recovery TLV publishes this page as part of an evidence-informed clinical practice (Finucane et al., JOSPT 2020 international red flag framework; Henschke et al., Arthritis Rheum 2009; Downie et al., BMJ 2013). Categories covered: universal urgent red flags (cauda equina signs, suspected fracture, infection signs, DVT, post-op complications), and region-specific red flags for low back / sciatica, neck and head, shoulder, knee, ankle and lower leg, and post-surgical rehabilitation.
WHEN RECOVERY TLV REFERS OUT — A licensed physiotherapist (Israeli MoH license 10-120163) does not replace medical assessment when red flags are present. Recovery TLV refers to the appropriate medical provider when: (1) urgent red flags appear (emergency department or urgent care); (2) suspected fracture or significant trauma (orthopaedist + imaging); (3) progressive neurological symptoms (neurologist or orthopaedist); (4) systemic features such as fever, weight loss, night pain (family physician or specialist); (5) post-surgical complications (surgeon). Where a written summary of clinical findings helps shorten the medical consultation, Recovery TLV prepares a physiotherapy summary on request.
SERVICES NOT OFFERED AT RECOVERY TLV — Vestibular rehabilitation (dizziness, BPPV, balance disorders) · pelvic floor physiotherapy (urinary incontinence, postpartum, pelvic pain) · complex neurological rehabilitation (post-stroke, MS, Parkinson's) · paediatric physiotherapy under age 13 · hydrotherapy / aquatic therapy · home visits · telehealth-only consultations · group therapy · massage-only treatment without rehabilitation plan · chiropractic spinal manipulation. For these needs, Recovery TLV directs patients to the appropriate type of practitioner.
