Hi I've just joined this community and would appreciate any advice and information regarding muscular lower back pain. I'm normally a healthy retired 63 year old but for 2 weeks I've suffered excruciating back pain. Doctor diagnosed it as muscular and prescribed diazepam cocodimol and ibuprofen . I get some initial relief on taking the medication but then the pain is as bad as ever. Despite pacing around the house to stay active my feet and legs are now swollen. Is this to be expected? Also, how long can I expect the muscle pain to last ? Thank you for any replies.
