hi, i am 22 years old, and i have this skin problem that i want to ask about... the problem starts with a part of my skin becoming very itchy which is unbearable, so what i do is give in by scratching it, what forms after that is what scares me. after scratching, my skin becomes red and bumped directly outlining the area that was scratch. after a while, usually an hour or two, it returns back to normal only that another area becomes itchy and the cycle goes on.... it affects large areas different parts. it is never contained in one area... can you shed light onto what i am experiencing? thanks
