Acute back pain often starts suddenly and can be alarming, but most cases improve within days to weeks with simple measures. Begin with sensible rest, avoid heavy lifting, and use over-the-counter pain relief as directed. Applying heat or cold packs can reduce muscle spasm and inflammation. Gentle movement and short walks help prevent stiffness, and our pharmacy team can recommend appropriate analgesics, topical gels, and when to see a clinician. If pain follows a fall, causes numbness, weakness, or loss of bladder or bowel control, seek urgent medical attention.
