Stomas have no sensation.
You can cut, bum, do anything to the stoma and you will not feel a thing. Stomas do not have receptors for pain. When people talk about pain from the skin around the stoma that skin, the peristomal skin, is full of nerve receptors which are sensitive to such influences as heat, cold, chemicals and adhesives that cause pain. However, it is the skin that senses the pain, not the stoma. Sometimes this lack of stoma sensation can lead to problems.
