He went to the doctors wensday and all she said was he has an ear and eye infection but he now has a red rash on his arms his fever is back his cough is 10x worse his nose is running worse and it's a nasty green color. He always say's his head hurts and every chance he gets he falls asleep. Should i take him to the ER? Should i take him back to the doctors? HELP!!!
