Thankfully I am very active and am still able to do trapeze and pole dance classes. On the day I go to my classes though, I need to take antihistamines so stop a rash that I get with exercise. It lasts maybe a hour but it is CHRONICALLY itchy and drives me mad! However, I have since started getting this rash with any activity... I literally just walked to my corner shop and back and now have this rash. Aside from antihistamines, has anyone found anything to stop this happening??? I don't want to be taking antihistamines everything I go for a walk!
