@sfedders . My husband has a Urostomy but I’m sure all kinds of bags have problems with leakage. As others have said, the skin must be dry. We use a hair dryer on low heat, then apply Nasacort (otc nasal spray) to help protect the skin, then dry again with hair dryer. While doing all of that, hold the bag with seal under your arm to warm the seal. Apply the bag and hold it in place for at least 30 seconds.

Take heart —- everyone here is ready to help.
