Need help please! My son has had a fever since Friday. That Friday he had a seizure. Went to the Er took blood test everything they say there's no infection. Basically he's riding it out . Today I started him on Tylenol. He had a rash on his cheek and belly . Dunno if it's because of the Tylenol or it's something else . He's barely eating just drinking . Any other ideas to keep the fever down . I tried cold bath. Shower wet cloth popsicle.
