try a chiropractor. He should be able to feel around your neck. There is a chance there is a pinched nerve causing the headaches - that was my problem. I also had a pinched nerve that disrupted my digestive system - once my body was properly aligned, I was good to go. Try it and see what happens.

You may have a twisted muscle from heavy lifting - you should see a physical therapist if u can - if not maybe a massage therapist to ease muscle cramps which may be whats wrong
go to the hospital and demand to see a real doctor and not just a family one, that is bad or get your doctor to refer you to a neurosugeon or something
