Hello friend! I also had this mysterious sharp pain that would suddenly occur without notice and was very uncomfortable and alarming. Mine wasn't gas. Because the pain was so random and fairly severe, I went to my GI doc. He could feel a small hernia under the stoma which many of us get, it just doesn't cause most stoma patients problems. But because mine was causing this pain, he sent me to a GI surgeon. The surgeon also agreed that because the hernia was causing me pain issues, I needed a stoma "revision". It was a fairly simple procedure and did not require another open abdominal major surgery. All he did was "take down" my stoma, removed the hernia that had developed underneath, and then "remade" my stoma as it was before. I stayed overnight in the hospital just as a precaution and went home the next day. The pain I had been experiencing has never returned (this happened in 2005) so the procedure fixed the problem. He did warn me, however, that if I ever developed another hernia under my stoma, that it would require the same procedure to fix it and he would put in an abdominal "mesh" under and around the stoma area for a better chance to prevent any further hernias from developing. Now let me also say that I am a registered nurse and often do a lot of lifting, bending, etc. in my career, so this may be why he was and is willing to give me more aggressive treatment and/or surgery if needed. And since I am a nurse and an ostomate since I was 19, I am sure they knew my knowledge and experience would not be an easy deterrent for any excuses or reasons on their part to not do anything about it. So please don't give up. You do not have to live with this pain if it is a hernia. Unfortunately, these days you and/or your family have to stand your ground and be your own advocate to get the proper health care you deserve. Please let me know if I can help in any other way. Good luck and God bless!
