What should you know about right lower back ache?

Pain may follow lifting, twisting, prolonged sitting, awkward sleep, or a change in activity. Tight muscles and irritated joints can hurt on one side. A disc or nerve problem may cause pain that travels into the buttock or leg, with tingling, numbness, or weakness. Lumbar spondylosis is one possible spinal cause; see the page on Lumbar Spondylosis for more context.

Right back pain can also be felt near the flank. Fever, nausea, urinary changes, or pain that does not vary with movement can point away from a simple muscle strain and deserves clinical review.

Keep gently active if movement is tolerable. Short walks and changing position regularly are usually more helpful than prolonged bed rest. Avoid heavy lifting, repeated bending, and twisting while the pain is irritable. Heat may relax tight muscles; use a protected warm pack for a comfortable period. A clinician or pharmacist can help you choose medicine safely, especially if you have kidney, stomach, heart, or pregnancy concerns.

Arrange an assessment if the ache is not settling, keeps returning, limits sleep or walking, or began after an injury. A clinician can examine your spine, hips, nerves, and abdomen before deciding whether tests are useful.

Seek urgent care for new loss of bladder or bowel control, numbness around the groin, progressive leg weakness, inability to walk, or severe pain after significant trauma. Prompt assessment is also sensible with fever, unexplained weight loss, a history of cancer, or feeling acutely unwell. Sudden flank pain with blood in the urine or vomiting also needs urgent evaluation.

Ask: Could the pain be coming from my muscles, spine, hip, kidney, or another source? Which movements should I limit, and which are useful? Do my symptoms suggest nerve irritation? What warning signs should make me seek urgent help? Would physiotherapy or an examination be appropriate if it continues?
