Hi, I recently just returned from xxxxxx, and have noticed a very strange looking rash on my back, it s like sun burn but only affects a specific part of my back, just above my right buttock, the rash is painless but I have become very tired and woozy, occasional nausea and stomach cramps and very achy. I have been back 3 days now and not sure whether I should see what happens or go to a doctor, thanks.
