I've had a lot of medical problems in my time, but currently I'm running on arthritis, gallstones and a cyst on one kidney. Oh, and diverticular disease which according to my urologist, everyone has. All of which combine for a pretty funky living experience, but I am baffled by a recent development; my urine has started to give off a powerful aroma of cheese. Not quite parmesan level, but maybe wensleydale. Personally I'm relatively stink-free (though my sweat sometimes smells like baby milk...), and it flushes away, but it bugs me. Is it normal, something to do with my gallstones, or what?
