AS treatment combines daily exercise — the single most important self-management step — with medication to control inflammation and prevent spinal fusion. In the UK this is a rheumatology-led pathway, not a one-off pain-clinic injection.
Treatment approaches
Daily spinal exercise
Mobility, stretching, and posture work are the foundation of AS management — NASS treats this as daily medicine, not an optional extra.
NSAIDs
First-line pharmacological treatment, often taken regularly rather than as needed so inflammation stays down overnight.
Biologic therapies
Anti-TNF and IL-17 inhibitors for active disease that doesn't respond to NSAIDs, started through NHS rheumatology.
Specialist physiotherapy
NASS-recommended structured programmes maintain spinal mobility and teach safe extension work.
Hydrotherapy
Particularly helpful for stiffness and supported movement when land exercise feels too sore.
Surgery
Rare but considered for severe spinal deformity or hip involvement after specialist review.
How UK treatment is stepped
Most people start with a regular NSAID plus a daily mobility routine while awaiting or attending rheumatology. If disease activity stays high — ongoing night pain, raised CRP, or MRI inflammation — NICE-aligned practice is to consider a biologic rather than adding stronger opioids. Smoking cessation is part of treatment: smoking is linked to worse radiographic progression. Steroid injections can help a stubborn sacroiliac or peripheral joint but are not a long-term spine strategy.
What to ask in rheumatology clinic
Useful questions include: is my disease currently active on bloods or MRI; should I take NSAIDs every day; am I eligible for a TNF or IL-17 inhibitor; and can I be referred to hydrotherapy or a NASS-linked physio class. Ask about bone health if you have been less mobile or used steroids. Bring a list of eye episodes and gut or skin problems — they change the extra-articular picture.
Treatment is not the same as rest
Resting a stiff AS spine makes it stiffer. Short rests during a flare are sensible; days in bed are not. The treatment page exists because people still hear 'take it easy' from well-meaning relatives. Pair any new medicine with the exercise page so the two plans do not fight each other.
