three days ago I woke up with a red bumpy very itchy rash on my right foot. It looked like an isect bite....after few hours more patches came up, this time on my elbows, knees, and hands. Yesterday some patches disappeared without leaving any track, but more and more appeared all over my body, including my mouth. I went to see my doctor and he told me that it was due a possible infection, sent me to have some blood work and chest x rays. In the meantime I am taking benadryl but it's not helping.
Does anyone has any suggestions???
