Hello Doctor Two weeks ago, I had an atopic dermatitis, went to the hospital with the certainty that it was an allergy and that after consultation with a physician obtain medications to control it. I was given an injection of steroids and the rash seemed to disappear for 2 or 3 days. The doctor told me to check that things could have caused my allergy. After watch that if I could have used a new thing, I noticed that I didn't used products out of the ordinary, the same shampoo, same creams, toothpaste , even deodorant, same detergent, everything. Then I thought that perhaps it was the mites, so I change my sheets, everything, but every night after 11pm, the rash returns. I do not feel temperature or anything else, just itching. One night I decided to try the eruption and i did not take my medications just to see if the rash start to extended. But the rash disappeared half an hour later, as usual, only this time not even take medicine and did not even bathe. Single disappeared without taking anything. For five days, I had the rash every night after 11pm and a half hour later begins to disappear. Last night i have it at 3am. And 2 days ago i wasnt in home and i had the rash. I'm not pregnant, because the first day that i had the rash, had my second day of menstruation, and i had a normal period, as usual passed without anything unusual. I would appreciate if you answer me as soon as possible that start to worry and I dont have time to go check to the doctor, because I have work in the office. Take care, a greeting. Im woman 23 years old.
