I am 46 and living in Florida.  I have experienced these itchy patches for several years now, but this summer they are the worst ever!  This year they started on my right ankle.  Crept up my leg below the knee. They appeared on my lower right arm and fingers, then my lower left arm and fingers (just patches though) and no on the back of my left leg from the knee down.  They are many fluid filled blisters that itch intensely. They eventually dry up and go away (leaving no scar generally). I've been to a dermatologist who performed a biopsy and said it was maybe...well, probably a reaction to a medication. No!   Today I was then told it could be an allergic reaction to something or maybe it's scabies.  So I'm about to put a lotion all over my body and leave it on for 12 hours and then wash it off- hoping to kill the mites.  I'll TRY anything at this point. I use to think I was allergic to Carolina Creeper, but I haven't been in contact with it.  Especially not for the past 8 summers.  The doctors don't seem to know what it is.  I would love to know the source and especially the solution. Help!
