Talk to Gastroenterologist on Stomach Problem

I have had this problem for 10 years. I cannot eat any kind of food or fruit that is sour or acidic. The only things that I can eat are apples, boiled rice and plain macaroni. There is a very bad pain in my shoulders, back, stomach and chest. The examinations show that I have H-pylori and a stomach scratch but I think there is a bigger problem. I have a headache always, everyday, very sever headaches. My knees and legs hurt at night and mornings. Please give me an answer as soon as possible because I am looking for a doctor and will come to your hospital if you instruct.
