If you've been assured that these are not epileptic seizures then, you may be suffering from an entity known as non-epileptiform
seizure disorder. There is an excellent link with lots of information on this entity which you will find very interesting which may answer many questions you may have about this disorder which is treatable but NOT with drugs that are typically used for
epilepsy...and boy are YOU LUCKY for that! Here is the link:

As far as the
sinus infection is concerned my guess if you are getting the read from either CT or mainly
MRI they usually report the presence of CHRONIC SINUS MUCOSAL THICKENING which DOES NOT mean that there is any active infection going on in the
sinuses. They simply make the call of something they see but it is not an acute infection and so you need not worry about treating such an entity since it has nothing to do with your spells.
