@dorma I can relate. I have had these symptoms at times but never for as long as you have. In my case it has turned out to be a urinary tract infection. I too have a history of other stuff: diabetes, chronic kidney disease (CKD) and I’m post pancreas transplant. I am immune suppressed on purpose to protect the transplanted organ. Whenever I don’t feel well &/or have a fever I get myself checked out if the symptoms don’t resolve in a few days. I’m sorry that your doctors have been unresponsive to your symptoms. When you describe these symptoms to them could you also ask if these symptoms could be related to your “other issues going on, requiring several procedures”? If they are treating you for these issues and responsible for the procedures perhaps this will get their attention?
