My 7-year-old son, for the past week, has had a headache, vomiting
, fever blisters, pus pockets in the throat, and fever between 100 and 103. Between this and his anxiety, his heart has been racing abnormally fast. Now he complains and cries of his chest hurting. His pediatrician believes the muscles are sore from the fever. First of all, does this sound like an appropriate diagnosis, and secondly, what can I do to alleviate his pain? Thank you!
