I Suffered From 2 Major Falls In The Spring, In

I suffered from 2 major falls in the spring, in each of these I banged my head rather severely. I began having with my bladder, sleepiness and fatigue. The bladder problems have cleared up, but I have been experiencing periods of exhaustion,nausea,extreme intolerance of a food smell..different each time I have a"Spell." these "spells" occur without any warning and always start with an extreme negative reaction to one smell. The neurologist says there is nothing wrong and that they are non-specifis seizures.
