How Can a Physio Help? What Physiotherapy Can (and Can't) Do for You
Wondering what a physio actually does, and whether you need one? Here's how physiotherapy can help, what the research says, and when to book.

A physiotherapist works out why you're in pain or not moving the way you should, explains what's going on in plain English, and gives you a plan to help you recover. That usually means hands-on treatment, targeted exercise and clear advice you can use between appointments. You can see a physio without a GP referral, and you don't need to be in severe pain, or have had a dramatic injury, to benefit.
What does a physiotherapist actually do?
Physiotherapists are regulated healthcare professionals who specialise in movement and function. In musculoskeletal physiotherapy, which covers your muscles, joints, tendons, ligaments and nerves, a good session tends to do four things:
- Assessment: listening to your story, testing how you move and how strong you are, and explaining what's likely causing the problem.
- Hands-on treatment: manual therapy and soft tissue work to ease pain and stiffness and help you move better.
- Exercise and rehab: a programme built around your goals and progressed as you improve, rather than a generic sheet of exercises.
- Advice: what to do (and avoid) day to day, how to manage training or work, and what to do if it flares up.
What can a physio help with?
Physiotherapy can help with a wide range of problems, including:
- Back pain, neck pain and sciatica
- Shoulder problems, including rotator cuff injuries and frozen shoulder
- Knee, hip and ankle pain, sprains and ligament injuries
- Tendon problems such as tennis elbow and Achilles pain
- Sports and training injuries
- Rehabilitation after surgery
- Arthritis and ongoing joint stiffness
It isn't only for injuries. Many people see a physio to stay active, return to training safely, or sort out a niggle before it becomes a bigger problem. You can see the full list on our services page.
Do I need a GP referral to see a physio?
No. In the UK you can book a private physiotherapist directly, without a letter from your GP. On the NHS it depends on where you live: some areas let you self-refer, while others ask you to go through your GP first, and waiting lists can be long.
Research from Keele University found that letting patients see a physio as their first point of contact raised no safety concerns, and didn't increase demand on services. If your physio thinks you need further investigation or another type of specialist, they'll refer you on. Whoever you choose, check they're registered with the Health and Care Professions Council (HCPC).
What does the research say?
The evidence for physiotherapy is strongest where it matters most for everyday pain and movement problems:
- Exercise should be a core treatment. A national review commissioned by the NIHR, covering physiotherapy for musculoskeletal conditions, found overwhelming evidence that exercise and activity are effective for musculoskeletal pain. These conditions affect more than one in four people in the UK.
- Personalisation matters. A 2026 review of rehabilitation research found that exercise therapy supports pain and function in selected conditions, but that the best dose and who benefits most are still uncertain. That's exactly why a plan built around you tends to beat a one size fits all approach.
- Seeing someone early may help. A systematic review found limited-quality evidence that for spinal pain, starting physiotherapy early was linked with lower costs and fewer opioid prescriptions, scans and surgeries, without worse outcomes for patients.
- Some discomfort during rehab isn't necessarily a bad sign. A 2025 review of trials in chronic musculoskeletal pain found no clear difference between exercise that causes some pain and exercise that doesn't, although the certainty of the evidence was low. Your physio will guide you on what's right for your situation.
When should I see a physio?
Good times to book include:
- Pain that hasn't started to settle after a week or two
- A niggle that keeps coming back
- An injury from sport, training or an awkward moment
- Stiffness that's getting in the way of work, sleep or daily life
- Before or after surgery
- Wanting to return to training or an event safely
You don't need to wait until it's unbearable. Earlier is usually easier.
Some symptoms need urgent medical attention rather than a physio appointment. Call 999, go to A&E or call NHS 111 if you have numbness around the saddle area, loss of bladder or bowel control, new or worsening weakness in your legs, severe pain after a significant fall or accident, a hot swollen joint with a fever, or unexplained weight loss alongside pain.
What happens at your first appointment?
Everything starts with a free, no-obligation consultation, where you tell us what's going on. From there, you choose a 30 minute, 60 minute or multi-week booking depending on what you need.
In your first session we'll talk through your history and goals, assess how you move, explain what we think is going on and what a realistic recovery looks like, and start treatment where it's appropriate. You'll leave with a clear plan and exercises to start on straight away. Wear comfortable clothes you can move in.
How many sessions will I need?
It genuinely depends. Some people leave their first session with a clear plan and need little more than a check-in. Others need a few weeks of treatment, and rehab after surgery can take longer. We'll give you an honest view of what to expect after your assessment, and the aim is always to get you confident managing things yourself, not to keep you coming back.

Your questions answered
Can a physio diagnose my problem?
Yes. Physiotherapists assess and diagnose musculoskeletal problems. Many can be worked out from a thorough assessment without a scan, and if you do need one, we'll refer you.
How is seeing a physio different from seeing my GP?
Your GP is the right person for medical diagnoses, medication and anything that could be serious. A physio specialises in movement and musculoskeletal problems and spends longer on assessment, hands-on treatment and rehab. The two work well together.
Will physio hurt?
Treatment shouldn't be unbearable. You may feel some discomfort during certain techniques or exercises, and you're always in control. Tell us if something feels like too much.
Do I need to be injured to see a physio?
No. Many people come for ongoing aches, stiffness, or help returning to training or activity.
