DS felt poorly on Saturday afternoon and suddenly had a fever of 101.7. He had a headache and sore throat. Sunday morning, he had a fever of around 100 and his throat was super sore so we took him to the urgent care thinking he had strep. The doctor there diagnosed him with Coxackie virus (the virus that causes HFM) but said he had herpangina which is like HFM of only the throat. She said 24 after his fever was gone he should be good. Well he stayed home Monday and Tuesday and had no fever on Tuesday and was feeling great so today he went to daycare. He was perfectly fine if not a little worn out at the end of the day but suddenly after dinner he started screaming that his head (brain, he said) was hurting so bad and also his arms and legs and then he vomitted everywhere. He fell asleep early while I was reading him a book. I am concerned about his headache, vomitting and lethargy after having seemingly recovered and I don't know if I should wake him and take him to the ER/urgent care or just monitor him all night. We have an 18 month old too so it isn't super easy to just spend all night in an ER... Any thoughts or experiences????
