My mother had undergone a ERCP and put a stent and also after a week leproscopic surgery for removal of gallstones and gallbladder was removed in the surgery to avoid formation of stones again during Nov 2013. She was suffering from sevier stomach pain before this. Post surgery she was alright and stent was not removed post surgery. Now from past two weeks n few months back again she is getting the pain which gives problem to breathe freely n suffering from pain. She was taking omez tablet wen she gets a pain and she will be alright. But from few days even that is not working. Kindly suggest what to do.
