Morning, my 3 year old son suffers with chronic sinusitis. For the last 5 months has been on 4 different antibiotics.Been using Vibrocil, Steroid spray and Allecet. Nose blocks up and he can't breathe. Only medication that seemed to help was Celastamine, which almost immediately cleared the nose and he was fine for 3 weeks. Now it has started again, nose blocked, running etc. Not sure what more we can do?
