Why stretching, massage and rest have not fixed it.
Sciatica is usually a pattern, not one tight spot. An irritated nerve, a stiff lower back and glutes that have stopped doing their share feed each other, often for months. A massage calms it for a day. Stretching hard can make a sensitive nerve angrier. What changes it is settling the nerve, then building the back and hips up so they can take your day again, with someone checking it is working. That is what the programme is for.
The Achilles Method: one practitioner, three phases.
1
Assessment
We find what is irritating the nerve, and check for anything that needs a doctor first.
2
Tension Release
Hands-on treatment to settle the lower back, the glutes and the path of the nerve down the leg.
3
Strength Rebuild
A loading plan written for you, so your back and hips can take your day and your training again.
Your plan is explained in the room and given to you in writing.
Prices: two ways to start.

Questions before you book.
About the programme
Can I book the whole programme now?+
Yes. Book it online and your first session is The Cornerstone. If the assessment shows the programme is not right for you, we refund everything except the assessment. You can also cancel within 14 days of booking and pay only for the sessions you have used. Prefer to meet first? Book The Cornerstone on its own, and if you go ahead the £120 comes off the programme.
Do I have to stop training?+
Usually not entirely. Stopping completely tends to leave the back and hips less able to cope, so it flares again when you go back. We agree what you can handle at your assessment and adjust your running, lifting or classes around it.
How long does it take?+
The programme usually runs over eight to ten weeks. Nerve pain can be slow to settle, and your assessment sets the length for you. You leave with the plan to carry on.
What if it is not working?+
If it is not moving, the plan changes, or we refer you on.
Is Alexander a physiotherapist?+
No. Alexander is an ISRM Level 5 Soft Tissue Therapist, not a registered physiotherapist. Physiotherapy on this site describes a type of service, not a registration. If your case needs a registered clinician or a doctor, we tell you and refer you.
Can I claim on health insurance?+
We do not work with private medical insurers. We provide a full receipt and a paid invoice for every session, so if your policy or health cash plan reimburses treatment, you can claim it back yourself.
About sciatica
What is sciatica?+
Sciatica is pain from an irritated sciatic nerve, which runs from the lower back through the buttock and down the leg. The word describes where the pain travels, not what is causing it. Finding the cause is what the assessment is for.
Is it always a disc?+
No. A disc pressing on a nerve root is one cause, and most of those settle with time and the right loading. Overworked muscles around the hip, long hours sitting and how you move can all keep a nerve irritated.
Is it always coming from the back?+
Not always. One of our clients, a marathon runner, had sharp pain from the glute to the ankle. The assessment showed it was the nerve, not a tight muscle, kept irritated by how his foot and pelvis were loading. You can read his case on our case studies page.
Do I need a scan?+
Usually not. UK guidance does not recommend routine scans for sciatica unless the result would change the plan, for example if symptoms are getting worse or surgery is being considered. We will tell you if your case needs one and refer you.
Should I rest until it settles?+
No. Bed rest tends to slow recovery. Keep moving within what feels manageable, and let the assessment set what to build up next.
Who gets it?+
People who sit for long hours, runners and lifters, and anyone whose back pain has started to travel into the leg. It is most common in your forties and fifties. We see it at both clinics, in Kings Cross and in Hampstead, and the assessment and the programme are the same at each.
When does sciatica need a doctor?+
Go to A&E straight away if you have numbness around your genitals or bottom, trouble passing urine or controlling your bladder or bowels, or weakness or sciatica in both legs.
See your GP first if your leg is getting weaker, if you cannot lift the front of your foot, if the pain follows a fall or injury, if you feel unwell or feverish, if you have lost weight without trying, if pain is constant and worse at night, or if you have had cancer. We screen for all of these at your assessment and refer you on if your case needs it.
