I have exercise induced urticaria. I want to know if anyone else has this and if so what causes it and what can you do to control it without a prescription. I am desperate. I am a runner that does not want a prescription. I suffer from asthma and the hives are worse when my asthma is worse. I am not taking anything for asthma except for an inhaler at the moment. I am tired of depending on drugs. I know that may sound ignorant but I want to help myself to help itself if you know what I mean.
