Hi,
Yes, very familiar symptoms, I had a concussion from a car accident at the end of March and haven't felt right since

I also get that surreal feeling, dizziness, light sensitivity, headaches etc..
I am a climber and trail runner so used to being very active and right now all I can do is walk on a flat surface but not too far as the dizziness and severe headaches start, oh boy it 1/2 killed me when I was told no climbing or running but I learned the very hard way that advice was right.
Rest is very important, the sticky on Vitamins is very good, eat well etc.
I'm in vestibular therapy, PT and neurological OT for my eyes, for a few months I felt exactly the same but just this last week I can feel a little difference so it all takes time.
Good luck, feel better
