I have been to many doctors for the same thing. I am a 28 yr old female, i have sever pain in the back right side of my head, sever back pain with difficulty moving and pain, heaviness, and numbness in my right arm and leg. I keep asking for test and the only thing they will do is an xray then tell me there is nothing wrong and that i am just looking for pills. I just want to be able to have my life back please offer some enlightenment as to what it could be.
