Here you have told you have dot spinal multiple level problem. To help you more I need to know what problem it is? Is it a spinal cord damage ? , is it a spine fracture?, and since when it is like that ? Are you on a rehabilitation part or it is damage permanant ? I have seen many patient with post accident spinal fracture or damage at spine. Few of them recover if there is no damage at spinal cord level. And few of them will not when there is a damage at spinal cord level. Since it does not have healing capacity once it is damage. To answer your question Dont take suggestiin on pain killer with chemist. Check with your treating doctor. Since he know your case well enough he will be in a better position to guide you. As well I also want to let you know most of my patient with spinal injury use to complain about a lot of pain in muscles while recovering stage. And I have treated them with physiotherapy stretching exercises and strengthening exercise based on the level of injury at spine. With this I have seen patient gets very good relief and sleep also. So you can also follow the same. I also suggest to use hot pack on your muscular painful area. Understand one thing pain is a symptom and not a problem. Here you need to treat the problem rather then symptom. Yes you can take some pain killer for time being till the time you recover and the medication suggestions best way can be given by only your doctor. So discus with him about your issues. Take care.
