I have a recurring skin condition that I've never gone to a dermatologist about. I get pimple-size, itchy, red, painful sores that usually develop pus in them and then they dry up after a few days to a week, if I put hydrocortizone cream on them. It's always in the same area- on my lower, left back, around my waistline. It starts out very itchy, and I know that one or more of these "pimples" are going to erupt that day or next. I've had this recurring condition for 20 years now. What brings it on is: clothing, like wool or something itchy on my skin; sunlight or sunburn, tanning beds, heat, and sometimes stress. I get it throughout the year. Any diagnosis of what it is and what I can do to prevent it? Thank you.
Optional Information:
