I pulled the big muscle next to the wing bone in my back. this is the 4th day in tremendous pain. cant take a very deep breath. the muscle is very hard and large. could it be trapping a nerve that cannot function due the muscle. my dr. has perscribed hydroco/aceta 5-325 mg for severe arthritus pain. i refuse to take as perscribed . i take 1/2 twice daily , and only if i cant handle my body myself. this muscle is killing me. can my perscription be combined with diazepam (which was the rx about 4 mo. ago for muscle then. my dr. is on vacation for 2 more weeks. i am 76 and go 24 seven. this has certainly slowed me down. need your advise. tks so much. ms davies.
