I worked this summer outside. I was out in the hot sun in long pants and sleeves. I was working in the water and would go swimming. I noticed twice that after spending the day doing microscope work in our (not air conditioned) lab I had leg swelling. I was sitting for 8 hours (with breaks) and noticed the swelling when I went upstairs for the day to take a shower. I then had swelling in my hand when holding an ice-cream carton. One day, after icing my leg and holding a cold water bottle against my arm, I developed large wheals. Cold Urticaria was my thought. I saw an allergic who put me on Zyrtec twice a day (I also have taken singular for a year for asthma).
However, AFTER being put on Zyrtec, I noticed full back and stomach hives a few hours after a shower and blow drying my hair. I developed red splotches and some hives after going into ac on a hot day. I have random red marks on my body, hives in small amounts even when I am not exposed to cold or sweating. (Now I am at college, the condition worsened after I left my job for the summer).
This is all within a couple months of the first swelling. I now carry around an epipen. I am 20 years old. My mom used to get hives when she was my age that she describes as worse than mine BUT where well managed with antihistamines. Since I still have continuous reactions break through my meds, are these actually severe reactions that are being tempered? I am worried about severe reactions. I am supposed to take a long plane ride in a few months and am worried about reacting to the AC on the plane. I am afraid to exercise and shower and especially swim. As someone who wants to go into fieldwork, I am starting to think that this may not go away fast enough and I may need a Plan B. Thoughts?
