Re red rash after excercise just posted. following day i had red line on each leg where the possible hives has been? i am aftraid to excercise now. i took an antihistime tonight but worried as never had issues with excercise before?

The cause of this exercise induced allergic type reaction is elusive. The exercise releases histamines& other substances that cause hives,angioedema and other allergic symptoms. Sometimes certain foods plus the exercise provoke the reaction. I recommend working with an allergist to help you cope with this issue. In the meantime taking an antihistamine may prevent or relieve reactions.
