I have recently broken out with blisters on my face and on my arms. They seem to just appear out of nowhere, and then they either scab or the skin starts to peel off around the blister and it spreads!! Has this happened to anyone?? I am thinking it might be because of the heat and humidity in Thailand, but I have been here for 5 months already, and the blisters have only recently emerged! Does anyone have some suggestions to what is causing them!?

Can you post a picture of the lesions, it is very hard without seeing them to have an idea.

Also: do they itch? Are they painful to the touch?
