floridaman,

Welcome to NeuroTalk. It sounds like you need to rest your brain. Your work environment may be problematic. Bright lights, cognitive challenges, quick movements and brisk walking on hard surfaces can all be stressful on a concussed brain.

Try taking it slower for a day or two and see if you can survive a slower day at work. It not, time off will be worthwhile. Your time off will need to include quiet rest. That mean no stress, only mild cognitive challenges, minimal screen time, no caffeine or alcohol, etc. Others will add some points.

Read the sticky at the top titled Vitamins.... It has some good links at the bottom of the first post.

My best to you.
