ok I have been to my family doctor 5 times now. I have pain in my head, throat, jaw, my arms, from my belly button to my chest, collarbone, and my pelvis and waist. I also have been dry heaving and gagging. my doctor doesn t know what this is he has taken a normal blood test, chest x-ray, and stomach x-ray. this has been going on for about 6 or 7 weeks now. what could this be and what can I do about it, my doctor is starting not to believe me?
