I have recently (feb) developed a skin allergy , hives to something i 'am thinking cold air (weather) has something to do with it and maybe coffee , these seem to be the only common thing, by late afternoon the hives are gone and in the a.m when i wake up there are none, only after being out for a couple of hours and come back in and have a shower they reappear, when i went to a horse show last weekend it was only 9 degree's cel outside and only 3 degrees in the night and i was in a trailer with only a small space heater, i had them come out late morning ( after coffee ) and shower, i was very cold and it was windy, i was covered in hives they were everywhere. Once i got home they have been less and today hardly any and i didn't have any cofee either but it has also warmed up too! I have had skin testing and i tested mildy to maple , poplar , dust mites , cat , pollen and ragweed. But no allergy to foods although i found i had big bumps about 15 min after leaving allergy testing on my food allergies but she said it was a neg testing after 15 min when she checked. I'm not sure where to go from here is it possible to have a delayed reaction ? Should i get tested for chemicals to , maybe blood test for food allergies i feel as though i need ti investigate further but i don't no where to begin.
allergist said that the cat / dust mitething would not present as hives more like stuffy nose is this true for everyone ?
