. Finally, after many months of migraines and pain in my shoulders, arms and back along with my neck I couldn't deal with it anymore and went one more time to the dr. She states she believes it is myofascial pain syndrome and suggested a tens unit and medications-flexaril, ibuprofen and vicodin. I have taken vicodin before and it doesn't touch the pain. What are your suggestions for this situation-oh, she also suggested a pain specialist for "trigger injections", have you ever heard of these injections? Do they work? Probably too many questions but am eager hear responses.
