My husband keeps getting recurrent pain in his neck. He has had to go to the ER a few times and x-rays were normal. He went to the dr. yesterday and she gave him Flexeril and Ultram but they don't seem to help the pain. Tonight I put hot, wet washrags (making them hotter slowly) and after waiting about 15 minutes, rubbed ben-gay on his neck and shoulder muscles. He says 'if I could just crack my neck, I think it would feel allot better'. Any other suggestions about what I can do to help him?
