theres a lot
of stuff
in there, leaving you many possibilities.
kidney stones, infection, bowel problems, ulcers, gallbladder, etc, etc, etc. also, a kidney infection doesnt usually show up when checking for bladder infection, but it can work down to the bladder. but theres many possibilities, so get to a dr, get bloodwork done, checking a broad spectrum of things. see if anything comes up and go from there.
