I am having a problem with my stoma. The area around the stoma becomes hard and when the output is going into the bag, there is a lot of pain., Wondering if there is a blockage in that area. Sometimes the pain fills like a knife. For the last 4-5 days, have been mostly on a liquid diet. Has anyone had this kind of problem. I had my surgery 30 years ago at Mayo Clinic (S. Mary's Hospital) and everything has been great, until the last year. About a year ago, I had a blocked intestine which I think was from taking iron pills because I had become anemic. I had to go go to the hospital and have that taken care of. There was a lot of pain then.
