I get itchy, bumpy rashes that come and go every once in a while. It always appears in random places on my body. I changed all of my sheets and put some freshly-washed clothes on. Besides my cat, there isn't anything that could possibly trigger an allergic reaction. (Though I was never allergic to cats) We don't even have furniture in the living room yet. My mom dusts, cleans, and vaccums the house every morning and night. We are generally cautious about dust mites because we have a sick baby. Is there anything I'm missing that could trigger this reaction?
