I have a serious rash on the face for 11 days and it keeps getting worse. I saw my dermatologist and she said it was from allergy, but I was taking antihistaminic drugs (Aerius), which she prescribed me, for 7 days and no change. I also have this rash on my arms, legs and chest but not like on the face. In Monday she prescribed me antibiotics (doxycycline) and I see no change to better. I'm feeling like my face will fall of. It burns and sometimes is itchy. I didn't have rubeola(Measles) or chicken pox as a child.
You can see the picture. Please if someone knows what this could be, help me. This is not acne. I had a clear skin while this didn't appear.
Sry for my grammar, English isn't my native language.
Thank you in advance.
