Suggest Treatment For Multiple Lesions On Her Lips, Face And Tongue, High Fever, Body Aches, Conjunctivitis In Both Eyes, Nausea, Sore Throat And Congestion

My granddaughter. Since last Friday she has developed multiple lesions on her lips, face and tongue. She has a high fever; painful body aches; conjunctivitis in both eyes; nausea; sore throat and congestion. Initial diagnosis is pneumonia together with an allergic reaction to her birth control pills which she began taking 3 months ago to help regulate her period. I m not buying it! I m concerned for her life!! Please help.
