Hello everyone! I am a 19 yr 108lbs female. For the past 3 years I have battled constant hives, they occur when I'm hot or exposed to cold. I went to the doctor who told me I would grow out of it. That was 2 years ago. I was prescribe hydroxyzine for the itching. In the past 4 months I took myself to a allergy specialist about it. They have put my on a daily dose of Allegra, Zantac, Zyrtec, and some other allergy meds. I take all of them through out the day. They help to prevent the bad episodes of hives but I may still get them at times. My doctor can not pinpoint the cause since I'm having reactions to both cold and heat. So another thing that has started in the past year I have constant nausea rather I eat or not I feel so sick I could vomit but I never do. I am also exhausted all the time. I used to work out at the gym but have no more energy to do so. My dr did do a iron test came back fine and then the allergy specialist did a plate off tons of test. My results were fine besides antibodies(I believe is what he said) were high around my thyroid. I asked him what that meant .he said it could be a number of things. I made them do another round of test for my thyroid today. I'm just so upset and disappoint I'm so sick of being sick. I don't get to enjoy the things I used to. I have to nap all the Time or I'm so drained I can't get up. It doesn't matter if I eat or not I'm always nauseated. I need advice.
