Anyone else BREAK OUT IN HIVES when they run?

In the summer I break out into hives every time I run. I run anyway. They only stick around for an hour or so and then they're gone. Very itchy, yes.

My thighs, stomach, and arms break out in huge, raised blotches of itchy redness after about thirty minutes of jogging. I gave up and now cycle. The moisture wicking cycling shorts and shirt reduce the masses to just a tinge of pink and no raised blotches or itchiness. To add higher impact cardio for my bones, I hike at our local nature trails once or twice a week too. For some reason, I do not break out when I hike.

Have you had an allergy test done? Might be some sort of pollutant that's more common where you are than in Alberta.

very odd. have you tried running indoors on a treadmill? did you get the same results? what about cycling outdoors?

try seeing an allergist.

if this persists, you're going to have take the benadryll on running days. if you only take it on days that you run, it should do any long term damage. i'd talk to the medical professionals though, and see what they think.

or you can find your way to the weight room.

My son has something like that. It's called cold urticaria. Sudden changes in temperature cause it,

I get hives ALL THE FREAKING TIME:

It's probably not from the running.

Its from the running outdoors. Or your fabric softener... you're actually allergic to it, but your skin doesn't freak out till it's wet in the clothes. Or its the heat, or the pollen in the air on your wet skin. Your skin is one organ. If one part of it is pissed off, generally it affects the WHOLE THING.

I would get an allergy test, or see a dermatologist. I solved my issue by running on a treadmill, because my issue was environmental & I never even knew it.

I can relate, I'm an Ontario transplant in Alberta and all my hives wentaway when I moved out west. Most likely if you are like me you have an absolutely wicked intolerance to Birch. It is however possible to have an immune response to exercise, though incredibly rare. Most likely they would tell you it was idiopathic anaphylaxsis and send you for allergy tests.

Good luck, you're not crazy! :-)

You absolutely should see an allergist, the sooner the better. I, too, suffer from heat induced allergies. It took me years to put together the triggers and then I finally went to an allergist. I didn't think it was possible to break out from head to toe hives from running. I now have progressed to going into anaphylactic shock. The attacks are now causing breathing difficulty and my blood pressure to drop. If it drops low enough, I could die. NOT GOOD!! My triggers are from bread or cheese and my body temperature rising from working out! I have had bread with no exercise and everything is fine. It is the combination of cheese or bread AND temperature change. My doctor told me to eat nothing before working out, I take a daily allergy pill and I carry an EpiPen everywhere I go. One cannot control their body temperature. Your trigger could be food or beverage, something you are washing or drying your clothes with, body lotion, outdoor allergens, etc., in combination with your body temperature rising. The problem with allergies is that the more your body is subjected to the "offender" the more your body attacks it and thus the hives are worse each and every time. They can eventually get to a point where they are life threatening. If you have noticed they have gotten worse during or after working out, please, please see an allergist and have some simple tests done, it is no big deal and not painful. It very well could save your life!!!!!
