I have really bad allergies, I am allergic to everything. My question is this. When i go thru a sneezing fit, i smell chlorine. What is that?? My sinuses dont feel full due to sinusitis I have read it can mean seizure activities too, I have seizures, meds keep controlled, and i dont feel ANY seizure activity at all, and I do usually know if i am gonna have one. This happens frequently, and I am just curious as to why the chlorine smell.
