Nasonex Seizures, Tonic Clonic Seizures, Swollen Sinuses, Running a Fever, Sinus Infection

My son has epilepsy. Last year I remember him being put on antibiotic and nasonex for his sinus infection, (Sept. 2008) he had 13 tonic clonic seizures in one day!
This year, he has been put on antibiotic and nasonex again (2 sprays in each nostril twice a day) and he had 4 tonic clonic seizures in one day!
I believe it is from the nasonex that his seizures has increased so much. He has been constipated, swallowing like his throat hurts, very swollen sinuses, acts like he is depressed, squints his eyes like he has a headache. The worse thing is he cannot tell me something hurts, he cannot communicate much at all because he is special needs. I can only go by his body language or if he is running a fever. This morning I did not give him the nasonex, I used only saline spray to rinse his sinuses. After reading everyone's side effects I went and threw all the nasonex in the trash!! My son will go to ENT on Monday and the ENT better not tell me to put my son back on nasonex because I will not do it!! I will only be using saline spray from now on on my son's sinuses.
