Welcome to NeuroTalk. Also, welcome to the club of being treated by doctors who are often clueless about concussions.

Your sensitivity to running impacts could mean you have injured your neck. Upper neck injuries are quite common to concussions. The head bone is connected to the neck bone. Your throat feeling also suggests a neck injury.

If you are anxious about your new self-employment, a concussion will likely heighten that anxiety.

I suggest you take frequent breaks from the computer. Maybe 5 minutes out of every 30 minutes. Close your eyes and sit quietly for those 5 minutes. It should help.

My best to you.
