Yesterday morning my son (23 months) woke up gagging and threw up once. he felt warm but no fever later in the day his fever was 101.6 today he had bumps on his face and legs and arms still a fever and hes itching them. Today and yesterday was over 90 degrees outside, but we did not take him out at all. so im not sure if he could still have a heat rash inside the house where its 68 degrees w A/C on. or if he is getting the chicken pox. He has had these bumps for a few hours now and is getting more. hes irritable. Can i get some advice on what to do please?
