On two occasions now I have felt a cramp like pain in my upper stomach (just below the rib cage) after using the toilet (just passing water), it's not really painful, just uncomfortable but intensifies if I try to stretch (like bend backwards). Does anyone have any idea what this could be? I've also been using the toilet alot more but when I recently had a urine sample checked it came back ok even though the doctor said it was unusually cloudy and contained protein!
Any ideas?
