i used to get that a LOT! especially when i was wearing jean shorts and it was raining and every move made my skin itch and hurt, so i know how u feel. i dont' get it much anymore, but when i do i simply use cortisone-10 in the tube and dont' scratch. gets rid of the swelling, itching, and rash. when u wash the area in the shower dont' scrub just wash gently w/ur hands. dry and apply the cortisone. good luck!
