Sorry Jinx,
our posts crossed and now mine looks completely irrelevant ,maybe,to what you are going through.

In regards to sides of the brain being effected, I think it's possible that only one part can be effected.I have had such strange symptoms like that since I've had all the amalgams replaced & even before,such as memory loss,going blank,foggy head & dyslexic symptoms, all varying in degrees and at different times.
In regards to the suggestions by people about supplements,please don't underestimate the effects of mineral imbalances on your body& especially your brain,magnesium is truly incredible,
I recommend checking out the link from bg123.

When you are actually going through it though ,I know it feels very little comfort.
You are not alone with this,lots of others here,including me,have said they have similar experiences.

If you are really freaked out you should call a practitioner,it is their job to listen & take your symptoms seriosly.

Afew times I have also suspected that I've had a stroke of some kind.It was lonely and frightening but I never told anyone not friends family or doctor.Definitely have some kind of damage to my brain.But I believe we can all recover .
