What kind of doctor are you going to ???? If it's a General Practice physician I would get another opinion. I was having the same symptoms and I went to a GP and the blood tests said that nothing was wrong but I was still in so much pain. He suggested I go to a Rheum. and he took blood I told him that the GP did blood work and said that nothing was wrong. The Rheum. told me that the GP didn't know what to look for. After he looked at the results he told me it was lupus. I would be leery of anyone telling you your fine if you are in so much pain.
