I am experiencing rash in both armpits. It might be a heat rash. Have been using Aloe gel which which has helped soothe and reduce redness but still I still have the rash?

May need visit. Such a rash located in an isolated location usually means a local issue. This could mean an allergic response to a new deodorant, or something that contacted the area off your fingers when you scratch an itch. That could mean things as different as poison IVY or even a fungus.
