I have been diagnosed with skin urticaria, among several other things. The regular term is "Cold-Induced Hives." Basically, I break out in obnoxious welts and giant, itchy wheals when I'm either really cold (more frequently in humid weather) or even hot, sometimes stressed out.
I've always heard the cause for something like this is oftentimes never discovered. My question has to do with an event when I was in highschool as a junior. I used to mow this elderly woman's lawn every Saturday. One day, I was in her front yard and the vibrations from the mower caused a huge cloud of angry yellow jackets to come out of their nest in the ground, racing towards us. I was more concerned with swatting them off her rather than myself. I was stung several times and broke out in enormous swelling--more than usual. Soon after that, about a month later, I developed my condition.
Does anyone know whether or not that event could be related to my condition? The effects (hives/swelling) are identical, so I wonder if maybe that event triggered a change in my body and the way it reacts. It would at least give me relief knowing what probably caused it.
