Thanks.
My son (6yrs ) picked up a bug, and we still had the kid version of the spray and it's the only relief he got at night. We are on day 6 now, and Dr's could not find the cause.... but I figured it out last night - he added to his list of issues a sore eye and point to forehead "hurts" - pretty sure it's sinusitis
Did tests ie covid, flu and blood tests - all negative
Normally most bugs with Antibiotics, clears in a few days, never had 6 days straight issues like this.
Going ENT now.
