They would do a EEG for sure, but this is best done as close to when the seizure happens. Depending on what the EEG shows, they possibly could order additional tests to help determine cause…and the cause might have absolutely nothing to do with the cold or cold medicine.
I think your husband needs to make an appointment with his PCP.
If the medics feel an ambulance ride to the ED is necessary, why would this cost you so much…that’s a whole different discussion.
I’m sending you a PM.
