Many people get back pain but if you do have compression on a nerve root none of these suggestions will help. Talk to your doctor. If he confirms nerve root compression is likely demand an MRI to confirm or otherwise. If confirmed discuss with a spinal surgeon or a chronic pain consultant. We normally start with injections of local anaesthetics and steroids. The earlier you manage it the better. Meanwhile avoid bedrest, and keep active. Some drugs will help but they would ground you. Good luck
