hey this has happened to me for a while but i've never really thought anything of it. every time i ride and i'm really warm but it's cold outside, i'll come inside to where it's warm and a few minites later my arms will be speckled with a rash of small raised red dots that are fairly itchy, especially at the joint. i'll feel way too warm for ages. the lumps go away within half an hour or so and stop itching within about 15 mins but i have no idea what they are. if i have a shower they go away so is it something to do with my body being unable to regulate heat? it's really hard to get it checked out as they only apear sometimes so i'll have to try and induce them or something for the doctor to look at. this has been happening for ages btw, over a year and a half. anyone know what it could be? so far i have thought of alergy to dairy products, alergy to washing powder/fabric softener? i really have no idea so any help would be greatly appriciated. cheeeeeeeeeeers ladssssss Hudson.
