Boy, this sounds so much like my story. I just got hit in the head 6 days ago after recovering for the last two years.

Your symptoms can intensify from a minor bump or hit. Having suffered from concussions before, you are more sensitive to getting hit in the head.

For the next two weeks, I would just closely monitor how you improve and whether this was a full blown relapse of symptoms or something much milder. Nothing you can do except take it one day at a time, manage the anxiety, and be patient.

Absolutely make sure you don't work past a threshold of overstimulating yourself. Take it slow.

Either way, everything will be alright. Neuroplasticity, our magic word. Your brain will continue to improve. Breathe easy, and feel better!
