I noticed a rash on my inner thighs about 6 days ago and realised a few days ago that it was also on my underarms. It appeared a few hours after I shaved these areas so I put it down to shaving rash but I've never had shaving rash like this before so I'm starting to think it's something else. The rash is just small red bumps but the itching is unbearable and it seems to be covering a larger area than before. Any ideas what it could be or how I could treat it? I can't get to a doctors until Monday.
