I was tested for many types of allergies. After 1 intradermal test my arm had huge raised welts. That weekend I sat on my featherbed wet-after a shower. My buttocks and genitals began to instantly burn.I took the featherbed off, but ever since I ve been having reoccurring hives and rashes. On my butt, vaginal area, underarms, stomach, under breasts and on top too.
