My 6 yr old son has a headache, fever, shakes, nausea and dizziness. Finally convinced him to lay down and close his eyes. Just fever and headache. No Rashes. No neck ache. Earlier before all this, it was fever and little nausea, but commented that his arm fell asleep. Then his foot. Neither anymore, but laying it all out there. I took him in the CVS Sun Oct 12 as I thought he has strep on his bottom. He has been taking Amoxicillin. 9.4 ml 2x day. 10 days. Thoughts?
