HI, I have what feels like a stitch in my right side, just above hip bone. It started very occasionally but now seems to be present more regularly, for about the last month. If I change position, sometimes it is relieved but not consistently. I do not believe it is food related. I am not taking any medications. this is a new and somewhat unpleasant, something I can tolerate but do not want to ignore if it indicates clearly that something else is going on. Thank you
