I got home and I started to Itch on the right side of my face,and It feels hot. My ears are buzzing and I have a small headache and feel a little numbness on right ear and right side of face. I took 2 Benadryl and I my fingers and toes feel cold. had a cup of coffee this morning with 2 cinammen rolls but have not eating nothing else. I have drank 3 mineral waters, and now I feel a little anxiety. Could this be a allergic reaction?
