I too have been sick for almost 2 months. It started with a pain under my ribcage and thru to my back. I thought it was my gall-bladder and after many tests found out my gall-bladder was not emptying correctly, and so I had it taken out. The pain did not go away. I was still weak, night sweats, chills, etc. That was almost 3 weeks ago. Since I have talked to workmates/neighbors that have the same symptoms. All my blood tests come back fine. The Dr.'s have yet to find anything.
I am hoping and keeping in touch with the others with the same symptoms and am hoping they find something out. Hope you get feeling better, keep posting it you find anything out. I will too. Thanks!
