I use the Hollister two piece setup. I have recurring challenges with acne and allergic reaction around the site. I started adding flonase back in and today the stoma site looked much better after my shower. I also started a leg bag as I am back in the office five days a week. Great solution to reduce frequency of bathroom trips. But the first time I wore it I had a pus filled site and some allergic reaction. Those are now healing and did not return on the second day of using the leg bag.
