Eczema Treatment Care

i have a wierd allergy….. im allergic to sunblock and spf. if i come in contact with or use it, or even touch someone who is wearing it i’ll break out in a rash called dermatitis. it happened when i was younger, and my mom passed it off as nothing (it was when i used chapstick with spf) but a few years ago i had on sunblock and got a rash all over and my lips got infected and i had to go to the hospital. they put me on steriods (not those kind) but i still get it all the time and cant always go and get the perscritption. what could i use or how could i avoid this? it happens like, 5-7 times every summer

I’d had hives for about a month and didn’t know what from, so I made an appointment with my allergist, and he checked my blood. After a few weeks, he told me that I don’t have any allergies, but I have something called Contact Dermatitis. He said that it very rearly last for longer than a year. I’ve so far had them for half-a-year, and they are driving me insane! HELP! What should I do to help it or make it go away? They aren’t out all of the time, only when I scratch or irratate my skin. THEY ITCH!
