    Stinging skin when hot
    fgbrian posted:
    Whenever I get hot, my arms (mostly my lower part not covered up by clothing) stings, and sometimes my back as well. When going out of a nicely air conditioned building at 5 in the afternoon, the stinging starts almost immediately even under the shade. I even sting while taking a hot shower (although it takes about 10 minutes to start). And if I exercise, the stinging lasts just as long as my time exercising (even with me applying ice and cool water). A while ago I was in decent shape and didn?t have the problem, but ever since injuring my ankles I quit running and have gained some weight. Now that it?s summer it?s becoming increasingly difficult to even dread going outside. I even wait to exercise at night and it still hurts. I went to see a doctor a while ago and he said I had petechia, but that it wasn?t the cause of stinging. Instead of answering my question, he decided to make some money off of me by prescribing me anti-acne creams and leaving me clueless as to what is causing my painful stings, therefore I am here. Besides the petechia (which is a light case mostly on my upper arm where it doesn?t sting always) I have no visible reactions (i.e. raised skin/redness). I have not changed personal care products, and do not take any sort of medication. It hurts so badly and now my insurance has run out. Is there anyone that knows of anything that could help me? I went so far as to try benadryl on one of my arms to see if I noticed a difference and that didn?t work. I?m open to any options. Thank you!

    hello -- the weight/stinging connection seems weird to me, but have you considered that you might have developed some kind of allergy to the sun, your own sweat (some kind of autoimmune problem?), or to temperature above a certain level? actually, the weight/stinging connection, it occurs to me now, might be related not to the b change in weight but to the b timing of the change in weight, i.e., you quit running just at the time the weather got hot. this would support the idea of having developed an allergy to the sun, which i have read is not uncommon. was the doctor you saw a dermatologist? if not, it might help to see one. it might also help to see whatever kind of specialist it is who deals with allergies (i cannot think of the name right now). this condition sounds awful. i hope you can figure out what it is and how to relieve it. -- susie margaret
