Hello, Thanks for your query. Well looking into your problem I would like to tell you this there can be multiple causes but most common will be mechanical low back pain in which there is disc degenerstive changes and due to compression of nerves there is radiating pain which comes on and off as and when the nerve is affected . The main treatment of such pain is bed rest along with pain killers and muscle relaxants. Muscle relaxants can help with your symptoms if used in appropriate dosage in combination with a potent analgesic. You can get the appropriate drugs prescribed from your Orthopedician after examination. Meanwhile you can follow these measures: - If the pain is severe, you need bed rest till the pain resolves. - Get some analgesics prescribed and apply analgesic spray or ointments. - While resting, keep a pillow under your knees if it doesn t bother you. - Avoid lifting heavy objects. - Back strengthening exercises and stretching exercises daily as advised by a Physiotherapist. - Avoid exercises in times of pain. - Improvise your posture while sitting. I do hope that you have found something helpful and I will be glad to answer any further query. Take care
