My 6 year old grandson started being sick last friday. He vomited twice suddenlythen he developed a severe headace and fever, chills, later on that night he started complainig with his groin hurting crying in pain then he had light sensitivity. He was taken to the ER and they did blood test said he had a ear infection sent him home with Amoxicillun. Reason for blood test he had a deer tick on him 3 weeks ago but tge test came back negative. He has not had a headache or nausea/ vomiting since friday. He has had a low grade fever everday and developed a cough sunday night. Today he didnt have fever until this afternoon 99 to 100 and developed sore throat (pins sticking him is how he described it) and he has blisters indide his mouth on his cheeks and back of his throat . His throat is not swollen. What us your opinion?
