Headaches and neck pain

Hello
I wonder if you can help-

For about 5 years I have been experiencing problems with my neck, more recently my shoulder, front and back and now my arm. I experience a deep ache in those areas, a tingly sensation and lately a rash and burning on my inner arm.
At the same time I have had headaches, mostly on the same right side. I was treated for this with topiramate as the doc believed it to be migraine although not classical.(Stopped taking them-they didn't help.) I get a shooting pain from my neck into my head if I lean forward. I often have loose stools, often if I'm nervous. For a period of about two weeks I had what seemed to be indigestion. Sometimes when I breath in I get a strange sensation in my chest and neck, where the large muscle in the front usually aches. My chest usually feels tight and achey. I sleep well, have a busy homelife but at the end of the day I'm good for nothing. Do you think this could be fibromyalgia? (
