Hi,I am Dr. Shanthi.E (General & Family Physician). I will be looking into your question and guiding you through the process. Please write your question below.
I had blood drawn and within 24 hours I have a rash on the top half of my body. Is this an allergic reaction? I have no allergys and I have taken Benadryl and it has been almost a week now and seems to be slowly getting worse and is itchy still. What could this be?
