My son 12 years, having sore throat and fever from three days, on third day he started having itchy hands. his temperature went up to 101 F, but now since 8 hours its around 98.8F. his throat still hurts while eating and drinking and its red, is this itchy hands related to his sore throat ? He has not taken any antibiotics as year but trying home remedies like gaggle with salt, and drinking Luke warm water.
