medic,

You said "I take a multi vitamin with iron, b complex"

This is likely a very low dose compared to the needs of an injured brain. 2500 mcgs or more of B-12 would be good plus D-3, magnesium, and some others. Most common B complexes are very weak.

What state are you in ? You likely need the assistance of a Work Comp attorney who understands concussions and mTBI's.

What AD meds are you taking ?
