I was told by my doctor I had a skeletal muscle spasm which was radiating pain to my arm but I have been in constant pain for almost 3 weeks. Ive been given naproxen and hydrocodone for pain both not working for me and they have tried 3 different types of muscle relaxers also not working very well. Please tell me what I should do other than going back to the doctor? Is it normal for tghe pain to last this long everytime I went back the doctor told me I needed physical therapy but until I do will this pain remain?
