Posted in chat earlier but got ignored! So trying again: I ended up with a couple of gnat (or similar) bites Saturday (I was at the allotment for all of 30 minutes!) By Sunday they were really hot, had a large red ring around them, plus a further tender blotchy red area stretching up and down each arm. They have been pretty much like that since, sometimes calming a bit, then flaring up again. I have had bites before that have tracked which these don't seem to be doing, however, the large red blotchy areas and heat are bothering me. Would I be wimpy to get the doc to look at them if they are the same tomorrow, given the tracking bites always needed anti-biotics?
