I agree that you could have something going on with your kidneys. The Epsom Salts work for the flush, but are also very harsh to the kidneys. As an R.N. I suggest you go to your physician or emergency room ASAP!! You do not have typical symptoms of gallstones, and if it is pancreatitis, you could be in serious trouble!! Please don't try to be a doctor. Take care and let us know what happens.
