Low Back Pain & Sciatica — Physiotherapy in London

Most low back pain and sciatica is non-specific and recovers well with physiotherapy, exercise and self-management education, and our HCPC-registered physiotherapists provide NICE NG59-aligned care across our Soho, Liverpool Street and Marylebone clinics — without routine imaging, opioids or prolonged bed rest.

Low Back Pain & Sciatica

The concern

Low back pain is one of the most common reasons UK adults seek help, and most episodes are non-specific — meaning no single structure can be pinpointed as the cause. Sciatica describes leg pain, tingling or numbness following the path of the sciatic nerve, usually from irritation of a lumbar nerve root. NICE guideline NG59 (Low back pain and sciatica in over 16s) recommends exercise, manual therapy and self-management education as first-line care, and explicitly advises against routine imaging, opioids, prolonged bed rest and acupuncture for non-specific low back pain. At Physio and Performance, assessment first rules out the rare red flags, then builds an individualised plan around graded exercise and a confident return to your work, training and daily life. Most acute episodes settle within weeks; recurrent or persistent pain responds well to structured exercise rehabilitation supported by hands-on therapy. Reformer Pilates and progressive strength training are offered as exercise-based ways to rebuild trunk and lower-limb load tolerance, consistent with the NICE NG59 emphasis on staying active and exercising.

What drives it

  • Sustained postural loading — long desk hours, commuting or repetitive manual work
  • Sudden mechanical overload — lifting beyond current capacity or abrupt twisting under load
  • Irritation or compression of a lumbar nerve root, the usual driver of true sciatica
  • Deconditioning — reduced strength and movement after time off, illness or surgery
  • Pregnancy and the post-natal period, which alter how the lumbar spine and pelvis are loaded
  • Stress, poor sleep and low mood — well-evidenced amplifiers of pain perception
  • Recurrent flares from a long-standing weakness or an unhelpful movement pattern

Common
questions

When should I go to A&E for back pain or sciatica?

Go to A&E or call 999 immediately if you develop loss of bladder or bowel control, numbness around the saddle or genital area, or progressive weakness in both legs. These can signal cauda equina syndrome — a rare emergency needing urgent imaging and surgery within hours. Also seek urgent care after significant trauma.

Do I need an MRI scan for my back pain or sciatica?

Usually not. NICE NG59 advises against routine imaging for non-specific low back pain and sciatica, because it rarely changes treatment and often shows incidental findings — disc bulges or mild degeneration — that are common in pain-free people. We reserve imaging for genuine red flags or symptoms suggesting a specific cause needing further investigation.

Should I rest or stay active when my back or leg hurts?

Stay as active as your pain reasonably allows. NICE NG59 advises against prolonged bed rest, which slows recovery and raises the risk of persistent problems. Walking, gentle movement and keeping to your normal routine where possible are recommended even during an acute flare. Your physiotherapist will guide what to modify and what you can safely keep doing.

How long does sciatica take to get better?

Most sciatica improves over several weeks, and the majority resolve without surgery. With physiotherapy, an acute first episode of low back pain often settles within a handful of sessions, while recurrent or longer-standing pain responds more gradually over a longer course of structured exercise. Your physiotherapist will give you an honest, individual projection at your first appointment.
