Sounds to me like you might not be getting adequate clearance of toxins from your body. Buildup of uric acid crystals will cause these symptoms, along with some other toxins.
I would go back to the dr - ask them to check your renal function, and probably liver function also. If you have a stone that is blocking biliary ducts, you could be getting logged down with bilirubin, also.
Sincerely,
