I've recently started to come out in hives all over my body when overheated and rushing around. It's ONLY when the exertion has caused overheating. I never get them if say, I'm too warm because of central heating being too high.
I've had hives in the past so it's not brand new to me, but this time they seem to be accompanied by a headache. It comes on very suddenly and coincides with the hives. The headache does subside, but am vaguely concerned. Why would a headache come along with the hives?
The hives come on almost instantly, within a minute.
I'm not overly bothered, I guess, by the hives, just the headache.
Anyone had this?
