I've been having this red bumps on my back since high school. I'm 32 today. And since last year it has escalated from my back to chest, upper arms and neck. They often get pretty big, swollen, hurts and the skin underneath is very hard. When healed often leave a red mark. Sometimes I get on knees, lower legs, stomach and butt as well. Much less thou and heal much faster.
I've tried benzoyl peroxide 2,5% and 5% without any success. Different antiseptic shower creams and lotions. A steroid called betnovat with chinoform. That my local doc prescribed. Did nothing but ease the swelling. I've just began taking antibiotic pills (Tetralysal) against acne. Started this week thou, so no improvement yet. I'm also trying paula's choice salicylic acid 2%. I've taken out all milk from my diet as well. Scrub with a glove once a week.
I'm pretty much clueless how to treat this. Nothing yet has worked. And none seem to know what it exactly is. So feel free to enlighten me.
