Replying to Concussions and PCS

I've been having PCS (post-concussion syndrome) symptoms for over a month and a half now from a bad knee to face ski accident.. It's honestly been a hard time on the day to day not feeling like myself, It's been getting slightly better but some days i just don't know. Mostly light sensitivity and feeling "off". I've recently been doing physio to treat my eyes and neck and taking lots of rest but I can't seem to be getting the results i've been looking for. Anyone have any experience with post concussion syndrome and steps they've taken to get better.
