If it is a kidney stone, you want to get this treated before it gets to the urgent stage where you are vomiting non-stop and in a panic. I always thought the pain was from the movement of the stone but new research says, no, it is the swelling of the vessels and ureter with urine behind the stone that causes the pain. Someone here (
@bearmom maybe?) has tried a heavy duty vibrator to shift the stone enough to allow the urine to drain. (This has to be repeated until the stone passes.)
However, please consider that this may have nothing to do with a kidney stone. Pancreatic pain frequently presents itself as mid back pain, not abdominal pain. Ditto for other organ problems that one would think would cause belly pain, not back pain, including upper intestinal (uh, like at upper anastomosis). If you still have this tomorrow, consider getting in to see your PCP. Unless you're doing lamaze breathing because of the pain, it probably isn't worth the expense of a ER trip. (All insurance is different, but mine only covers post-op complications for unapproved bariatric surgeries for pneumonia, heart attack, uncontrolled vomiting, or exacerbation of pre-existing co-morbidities. It WOULD cover a kidney stone as no way can that be directly related to this surgery -- the army learned from our middle east desert warfare that kidney stones take 80-90 days to form.)
Good luck with getting this sorted out.
