If you have someone that can help you measure if your proprioception is off that might be useful. I had a concussion and my ability to accurately understand the location of my body was messed up.

Other thing you could do is test if you are hearing in the right direction. Close your eye and have someone take a clicker and make noise. Then point to where you think the noise is coming and see if it matches. Your injury may have messed that up as well.

I would do what you are doing exercise safely but also take

Creatine
Omega 3 (Good kind do some research on legit brands)
Magnesium

If I had my injury again I would dose those at the beginning good luck
