Skin care is very important for all the obvious reasons. If you have a lump, this is not any kind of a rash or skin problem that I've ever experienced. It maybe nothing, but Iwould recommend you talk to your doc about soon. I think anyone who is incontinent and wears diapers sooner or latter gets a rash.

There are a lot of protection creams on the market and I use A&D twice a day. Once in the morning after I shower, and again at night after I shower. With the onset any type of skin irritation I use a product called Butt Paste. Funny name but it works GREAT. Most of the time, Butt Paste takes care of any type of skin I get. However, a few times a year, I seem to need something a little better/stronger than Butt Paste that requires a doc's prescription. So far, my last line of defense that has worked well is a product called Clotrimazole Cream. This cream requieres a prescription and it has worked GREAT every time I've needed it.

Hope this info helps.
