My 19 year old son who is on allergy meds and advair inhaler, eyedrops ect. He has always had large size pupils. The other night his pupils were pulsing from large to regular size. He is also getting over a cold at this time. I know for a fact that he doesnt do drugs, so it couldnt be that. He did have seizures when he was around 2 they lasted for about 4 months, then went away as suddenly as they started, doctors had no clue what the cause was. Is this a sign of maybe the seizure activity trying to start back up?
