okay so I have been running for quite some time.... I am about to run my 5th marathon on sunday. But have been dealing with what my doctor is calling an Exercise induced allergy. my only symptom is hives. I only break out after about 7 miles. all my maintenace runs leave me unaffected but as soon as I go over 7 miles I get all hot and itchy. the concern is that I will go into anaphlactic shock and not be able to breathe..... it's only been going on for about 5 weeks, and each time I run my 10 miles I my hives get a little more intense and last a little longer.
I need to run this race on sunday... too much time and energy has gone into it, to stop because of hives!! I'm bummed out and am looking for any advice.
I have a similar issue with hives, but for me, it's more of temperature thing. After winter, when it begins to get warmer outside, I break out in hives at the end of every single run. It's almost unbearable. After a few weeks (once I'm acclimated to the higher temps), it goes away until the next year. I have never been able to find anyone who can tell me why this happens or if there is anything I can do to prevent it. Maybe someone on this forum can help us both.
