Rheumatoid arthritis in the back: what to know

Rheumatoid arthritis commonly affects peripheral joints such as the hands and feet; back pain may instead come from muscle strain, discs, wear-related changes, the pelvis, or another inflammatory condition. Pain that is worse after a particular movement differs from pain with prolonged rest or marked morning stiffness. Numbness, tingling, weakness, or changes in balance add useful information for assessment.

Keep moving gently within a comfortable range and change position regularly rather than staying in bed for long periods. Use a supportive sitting position, avoid lifting that sharply increases pain, and note the area affected, triggers, sleep disruption, stiffness and any limb symptoms. Ask your clinician whether physiotherapy, imaging, or an adjustment to rheumatoid arthritis treatment is appropriate.

Seek emergency care for new loss of bladder or bowel control, numbness around the groin, rapidly worsening leg weakness, or severe pain after injury. Prompt assessment is also needed for fever with severe back pain, unexplained weight loss, or pain that repeatedly wakes you and is worsening.

Which part of my back may be causing this pain? Do my symptoms suggest nerve irritation or inflammation? What movements should I practise or avoid while this is being assessed?
