Question

Why does my back hurt?

Why back pain happens, what usually helps in the first few weeks, how to stay appropriately active, and the NHS-aligned signs that mean you should contact a GP, NHS 111 or 999.

Why does my back hurt?

Back pain is very common and, in most cases, there is no single serious cause behind it. It usually improves within a few weeks, although it can come back. This page is general education, not a diagnosis of your pain.

Why backs hurt

Most back pain is described as non-specific, which means no single structure can be identified as the cause. It is often linked to a combination of everyday factors rather than damage:

  • Awkward lifting, twisting or a sudden movement.
  • Long periods sitting or standing in one position, including at a desk or driving.
  • Being less active than usual, or a sudden increase in activity.
  • Sleep, stress and low mood, which all affect how pain is experienced.
  • Being run down, unwell or tense for a prolonged period.

Sometimes pain travels from the back down the leg. Pain, numbness or tingling that runs from the lower back through the buttock and down one leg is often described as sciatica, which usually improves over time but is worth discussing with a GP if it does not settle.

Self-care in the first few weeks

NHS advice for common back pain focuses on keeping moving and managing pain enough to do so.

  • Stay active and carry on with daily activities as much as you can. Prolonged bed rest is not recommended.
  • Keep moving gently, and build back up gradually rather than waiting to be pain-free.
  • Try to continue working if you can; a phased or adjusted return is often better than a long break.
  • Use heat, such as a heat pack or a warm bath, for stiffness and muscle tension.
  • Consider over-the-counter pain relief if suitable for you. A pharmacist can advise on what is appropriate alongside any other medicines you take.
  • Look at sleep, stress and general activity levels, since all three influence pain.
  • Simple exercises, walking, swimming, yoga or pilates help many people, but choose something you can do comfortably and build up slowly.

Staying appropriately active

"Appropriately" is the important word. Activity should be uncomfortable at worst, not sharply painful, and you should be able to recover afterwards rather than being knocked out for days. If a particular movement reliably makes things much worse, ease off that movement rather than pushing through, and get advice.

Hands-on treatments

Some people find physiotherapy, osteopathy, chiropractic or massage helpful for back pain, particularly alongside staying active. None of these suits everybody, the response varies from person to person, and none should be presented as a guaranteed fix. If you choose to see a private practitioner, check they are registered with the relevant UK regulator or professional body, tell them about any other health conditions, and stop and seek medical advice if your symptoms change or worsen. A GP can also refer you to NHS physiotherapy, and in many areas you can self-refer.

When to contact a GP or NHS 111

Contact a GP or call 111 if:

  • The pain does not start to improve within a few weeks.
  • The pain is stopping you doing your normal activities.
  • The pain is very severe, gets worse over time, or is worse at night.
  • You have back pain along with a high temperature, unexplained weight loss, or a swelling or lump on your back.
  • The pain started after a serious accident, such as a car crash.
  • You are worried, or you cannot manage the pain at home.

Emergency red flags

Call 999 or go to A&E immediately if you have back pain together with any of the following:

  • Numbness or tingling around your genitals or buttocks.
  • Difficulty passing urine, or loss of bladder or bowel control.
  • Chest pain.
  • A high temperature.
  • Unintentional, unexplained weight loss.
  • A swelling or a deformity in your back.
  • Pain that is no better after resting, or is worse at night.
  • Pain that started after a serious accident.

These can be signs of a more serious problem that needs urgent assessment.

Practical next steps

  1. Keep moving and keep your normal routine going where you can.
  2. Use heat and, if suitable, over-the-counter pain relief so you can stay active.
  3. Note what makes it better and worse over a week or two.
  4. Ask a pharmacist about pain relief options.
  5. Contact a GP if it is not improving after a few weeks, or sooner if it is severe.
  6. Seek emergency care immediately if any red flag above applies.

If you and a clinician decide hands-on support is appropriate, you can browse physiotherapists, massage therapists and clinics in the Happy As Life directory and use search to find registered practitioners near you.

Frequently asked questions

Should I rest or keep moving with back pain?
NHS advice is to stay active and carry on with normal activities as much as you can. Long periods of bed rest are not recommended. Build activity back up gradually rather than waiting until the pain has completely gone.
How long does back pain usually last?
Most back pain improves within a few weeks, although it can return. If it is not starting to improve after a few weeks, or it is stopping you doing your usual activities, contact a GP.
When is back pain an emergency?
Call 999 or go to A&E if back pain comes with numbness or tingling around the genitals or buttocks, trouble passing urine, loss of bladder or bowel control, chest pain, a high temperature, unexplained weight loss, a swelling or deformity in the back, or if it followed a serious accident.
Will physiotherapy or massage fix my back?
Some people find them helpful, especially alongside staying active, but they do not suit everyone and no practitioner should guarantee a result. Speak to a GP or pharmacist first if you are unsure, and check any private practitioner's registration.
What is sciatica?
Sciatica describes pain, numbness or tingling that travels from the lower back through the buttock and down a leg. It often improves over time with the same keep-moving approach, but see a GP if it is severe, not settling, or getting worse.
Does stress affect back pain?
Stress, poor sleep and low mood can all influence how much pain you feel and how easily it settles. Addressing sleep and stress alongside gentle activity is a reasonable part of managing everyday back pain.
