My 6 yr old grandson has had a low grade fever last three days (99.6-100.5). He seemed to be improving after two days of rest; took a warm bath last night...i had the room heated, dried his hair, etc. so he wouldn t get chilled. Within one hour he had total nasal congestion...unable to breathe except through his mouth. I also ran a vicks vaporizer in the bedroom....but only got some relief after i went to pharmacy and got Delsym. Could that warm bath have triggered possible sinus issues?? He has missed a lot of school with sore throats, ear infections, etc. Also just lost a tooth. Him, not me!!
