Sciatica treatment: what actually helps, according to NICE and the NHS
Staying active, exercise and physiotherapy come first. A Liverpool physio team explains what the guidance recommends, what it advises against, how long sciatica usually lasts and when it is an emergency.
The sciatica treatment with the best support in UK guidance is not a pill or a gadget. It is staying as active as you can, doing exercise suited to you, and, if you need more help, physiotherapy that combines exercise with hands on treatment (NICE, 2020; NHS, 2024). Most people improve with this approach, although it can take weeks to months.
This guide sets out what the National Institute for Health and Care Excellence (NICE) guideline on low back pain and sciatica (NG59) and the NHS actually say: what helps, what is not recommended, which medicines NICE advises against, when injections or surgery come into it, and the symptoms that mean you should go to A&E straight away. If you are trying to work out whether your pain is sciatica or a buttock muscle problem, our article on sciatica or piriformis syndrome covers that.
How long does sciatica last?
The NHS says sciatica usually gets better in a few weeks to a few months, but it can take longer, and it can come back (NHS, 2024).
A large UK study followed 609 adults who saw their GP with back-related leg pain, three quarters of whom were diagnosed with sciatica. At 12 months, 55% had improved, meaning their disability score had dropped by at least 30% (Konstantinou et al., 2018). So many people get better within a year, but a sizeable group are still bothered by it, which is a good reason to get help early rather than waiting it out alone.
What helps sciatica: staying active and exercise
Keep moving
NICE recommends that people with sciatica are given advice and information about the condition and are encouraged to carry on with normal activities, at every stage of treatment (NICE, 2020). The NHS puts it simply: keep up your normal activities as much as you can, start gentle exercise as soon as you can, and avoid sitting or lying down for long periods. Moving may hurt, but the NHS says it is not harmful and can help you recover faster (NHS, 2024). Heat packs on painful areas can also help (NHS, 2024).
Sciatica exercises
There is no single magic exercise for sciatica. NICE recommends considering a group exercise programme tailored to the person's needs and capabilities (NICE, 2020), and the NHS lists exercises and stretches among the main treatments (NHS, 2024). In practice this usually means gentle movement for the back and hips, walking, and building strength and tolerance gradually as the leg pain settles. The right starting point depends on what eases and aggravates your pain, which is one of the things a physio assessment works out.
Sciatica physiotherapy and what NICE does not recommend
The NHS describes physiotherapy, including exercise advice and manual therapy, as one of the main treatments for sciatica (NHS, 2024). NICE is specific about how hands on treatment should be used: manual therapy, meaning manipulation, mobilisation or soft tissue techniques, should only be considered as part of a package that includes exercise (NICE, 2020).
For sciatica that is persistent, or where there are significant psychological or social barriers to recovery, NICE suggests considering a combined physical and psychological programme. Cognitive behavioural therapy can also be considered, but again only alongside exercise (NICE, 2020). Getting back to work and normal daily activities is part of the plan, not something to wait on until the pain has gone (NICE, 2020).
NICE also lists several treatments that should not be offered for low back pain with or without sciatica (NICE, 2020):
| Treatment | What NICE says |
|---|---|
| Staying active and normal activities | Encourage at every step |
| Exercise programme | Consider, tailored to the person |
| Manual therapy (manipulation, mobilisation, soft tissue) | Consider, only as part of a package that includes exercise |
| Belts or corsets | Do not offer |
| Foot orthotics | Do not offer |
| Traction | Do not offer |
| Therapeutic ultrasound and TENS | Do not offer |
Scans are not routinely needed either. NICE advises against routine imaging outside specialist settings, and says imaging should be considered only if the result is likely to change how you are managed (NICE, 2020).
Medicines for sciatica: what the guidance says
NICE updated its advice on medicines in 2020. It says gabapentinoids (such as gabapentin and pregabalin), other antiepileptic medicines, oral corticosteroids and benzodiazepines should not be offered for managing sciatica, because there is no overall evidence of benefit and there is a risk of harm. It also says opioids should not be offered for long-term (chronic) sciatica (NICE, 2020).
For anti-inflammatory painkillers (NSAIDs), NICE asks prescribers to be aware of the risk of harm and the limited evidence of benefit, and to take into account the person's risk factors for stomach, liver, heart and kidney problems (NICE, 2020). The NHS suggests asking a pharmacist about painkillers and notes that paracetamol is unlikely to help (NHS, 2024).
If you are already taking one of these medicines, do not stop it suddenly on the strength of an article. NICE highlights that stopping some of them can cause withdrawal problems (NICE, 2020), so talk to your GP or pharmacist first.
When are injections or surgery considered?
If pain is severe and other treatments have not helped, the NHS says you may be referred to a hospital specialist to discuss options such as an epidural or other painkilling injection, or decompression surgery (NHS, 2024).
NICE recommends considering an epidural injection of local anaesthetic and steroid for people with acute and severe sciatica (NICE, 2020). Spinal decompression surgery is considered when non-surgical treatment has not improved pain or function and a scan shows findings that match the symptoms (NICE, 2020). The NHS notes that surgery can sometimes help relieve sciatica (NHS, 2024). These are specialist decisions made after a proper assessment.
When to get checked urgently
When is sciatica an emergency? A small number of people with back pain and sciatica develop cauda equina syndrome, where the nerves at the bottom of the spine are compressed. It is rare, but it needs urgent treatment (Torbay and South Devon NHS Foundation Trust, n.d.). The NHS says to call 999 or go to A&E immediately if you (NHS, 2024):
- have sciatica on both sides
- have severe or worsening weakness or numbness in both legs
- have numbness around or under your genitals, or around your anus
- find it hard to start peeing, cannot pee or cannot control when you pee, when this is not normal for you
- cannot tell when you need to poo, or cannot control your bowels, when this is not normal for you
Do not drive yourself. Ask someone to take you or call an ambulance (NHS, 2024). Do not wait for a physio appointment with these symptoms. Our article on lower back pain red flags covers other warning signs.
See your GP if the pain has not improved after a few weeks of home treatment, is getting worse, or is stopping you doing your normal activities (NHS, 2024).
Frequently asked questions
What is the best treatment for sciatica?
UK guidance puts staying active and exercise first. NICE recommends encouraging normal activities at every stage, considering an exercise programme tailored to you, and using manual therapy only as part of a package that includes exercise. The NHS lists exercises and stretches, painkillers and physiotherapy as the main treatments. Injections or surgery are only considered by a specialist if severe pain does not improve.
How long does sciatica usually last?
The NHS says sciatica usually gets better in a few weeks to a few months, although it can take longer and can come back. In a UK study of 609 people who saw their GP with back-related leg pain, 55% had improved by 12 months. If your pain is not improving after a few weeks, or is getting worse, it is worth getting it assessed.
Should I rest or keep moving with sciatica?
Keep moving as much as you can. The NHS advises keeping up normal activities, starting gentle exercise as soon as possible and avoiding sitting or lying down for long periods. Moving may hurt, but the NHS says it is not harmful and can help you recover faster. Heat packs on the painful area can also help while you stay active.
Does NICE recommend gabapentin or pregabalin for sciatica?
No. Since 2020 NICE has advised that gabapentinoids such as gabapentin and pregabalin, other antiepileptic medicines, oral steroids and benzodiazepines should not be offered for managing sciatica, because there is no overall evidence of benefit and there is a risk of harm. If you already take one of these, do not stop suddenly. Speak to your GP or pharmacist first.
When is sciatica an emergency?
Call 999 or go to A&E straight away if you have sciatica in both legs, severe or worsening weakness or numbness in both legs, numbness around your genitals or anus, or new problems peeing or controlling your bladder or bowels. These can be signs of cauda equina syndrome, which is rare but needs urgent treatment. Do not drive yourself.
