I have been getting these red bumps over my thighs, butt, and inner arms. At first they seem almost pimple like but you can tell they aren t. After a few days they will start to dry out and turn brown, they last in this stage for a very long time. Will they re red they are raised bumps but when brown they are mostly flat. I ve gotten so many all around the same areas and recently in new areas as well. I was wondering what it could possibly be.
