What is chronic lower back pain?
Back pain is described as chronic when it persists beyond three months. In most cases no single structure is to blame; scans often show age-related changes that are equally common in people without pain, and the pain is best understood as a sensitised system involving joints, discs, muscles and the nervous system together. It is one of the leading causes of disability in the UK, affecting people of all ages, with work, sleep, stress, fitness and mood all influencing how much it intrudes on life.
Diagnosis focuses on ruling out specific causes: a clinician screens for nerve compression, inflammatory arthritis and rare serious pathology, using MRI selectively rather than routinely. For the majority, the diagnosis is non-specific chronic low back pain, which guides an active, rehabilitation-led approach.
Common symptoms
- Persistent aching or stiffness in the lower back
- Flare-ups triggered by activity, stress or poor sleep
- Pain that varies from day to day
- Difficulty with prolonged sitting, standing or bending
- Sleep disturbance
- Reduced fitness and confidence in movement
- Occasional spread of pain into the buttocks or thighs
How long will you wait?
NHS pathways route chronic back pain through MSK triage and physiotherapy, and waits for specialist pain clinics or interventional treatments commonly run to several months, against a national median wait of 12.4 weeks.
Privately, you can typically see a spinal or pain specialist within 3–7 days, with MRI within days and physiotherapy or injection treatments usually starting within 1–2 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- Exercise-based rehabilitation. Structured, progressive exercise, of almost any kind you will keep doing, is the most strongly evidenced treatment.
- Physiotherapy and manual therapy. Hands-on treatment can ease symptoms short term and works best packaged with an exercise programme.
- Pain management programmes. Combined physical and psychological programmes help people whose pain significantly limits life, improving function and confidence.
- Interventional treatments. For carefully selected patients, options such as facet joint injections or radiofrequency denervation can reduce pain from specific spinal joints.
What does private treatment cost?
As a guide, private physiotherapy typically costs around £60–£90 per session, facet joint injections around £1,500–£2,500, and radiofrequency denervation around £2,500–£4,000.
Does health insurance cover chronic lower back pain?
This is an area where policy terms matter. Insurers cover the diagnostic work-up, physiotherapy and defined treatments for back pain that begins after the policy starts, but back pain lasting beyond months is often classed as a chronic condition, meaning ongoing management is not covered even though acute flare-ups and specific procedures may be. Pre-existing back trouble is one of the most common exclusions applied at underwriting.
Frequently asked questions
Do I need an MRI scan for chronic back pain?
Usually not. Guidelines advise against routine imaging because scan findings such as disc bulges and degeneration are common in pain-free people and rarely change treatment. MRI is valuable when there are nerve symptoms, features suggesting inflammatory or serious disease, or when a specific intervention such as an injection or surgery is being planned.
Is it safe to exercise with chronic back pain?
Yes, and it is the single most effective thing you can do. Hurt does not equal harm in chronic back pain: flare-ups during exercise are common and not a sign of damage. The best exercise is one you enjoy enough to continue, whether walking, swimming, Pilates, yoga or strength training, ideally built up gradually with professional guidance at the start.
Can chronic back pain be cured?
For many people it can improve dramatically, and some become essentially pain-free, but honest clinicians talk about management rather than guaranteed cure. The realistic goal is a back that lets you work, sleep, exercise and live fully, with flare-ups you know how to handle. Combined approaches addressing fitness, sleep, stress and confidence deliver the best long-term results.
