Hi, sorry you deal with this. I have possible Erythromelalgia and have suffered many flares for years. My triggers are sugar, sodium, caffeine, stress, heat, sun, humidity and being sick. I usually can't wear sneakers if its too warm out. If you are a runner you could try buying breathable shoes, going sockless, or putting shoes/socks in fridge..but that would only last so long. Elevation, drinking cool drinks, personal fans, cool showers, diet seem to help most. I sometimes sleep with a ice pack under my neck at night to get cooled down, don't know why but it helps when lying down. Personally use a window Ac unit in my bedroom, game changer! I never use icebaths as this can cause tissue damage. I take gabapentin for my PN which I think slightly helps but have not tried anything else. Aspirin or ibprofen can be helpful but have to be careful of long term use and the stomach. That's what happened to me anyway, chronic gastritis, so no more Nsaids.
