I have begun suffering from solar uticaria - I can't even walk to the mailbox wearing a pair of shorts on a hot, sunny day without getting these awful, red, itchy hives on my legs that last for days! The other day, after suffering since the day before, I opened my medicine cabinet and saw my bottle of DMSO. I thought, "Well, what the heck" and dabbed some on my "spots". Guess what...the itching stopped within minutes and has never come back! The red spots are still there, but no suffering from the itching. And this was after just ONE application. Next time I'll continue the treatment and I bet the spots, themselves, will disappear.
