My adult daughter has a red, itchy rash on her upper chest area, upper back area, neck and cheeks. She has a 9 year old that has been taking Amoxicillin for Strep Throat. A few days into it taking this medicine he developed itchy, spotty rash all over his body. He was allergic to the medicine. My daughter was administering his liquid medicine to him and some of it got on her hand. She is allergic to it also. Could just getting it on her hand have caused this to happen to her upper chest, upper back, neck and cheeks?
