I have this. Same thing - I think it's gone and then I run and jump too much.

I think of it like this:

Picture a pure glass globe. Imagine that it had a significant impact. It didn't shatter, but there are cracks that need to be fixed.

I think of our brains like this post-concussion. Like there are micro-cracks that need to be put back together. For a lot of us, our original concussion may not have anatomically fully healed and that is why symptoms come back.

I've found certain things help. Diet is huge. PEMF, LLLT, and certain supplements help.

I saw a Matrix Repatterning doc for a while. He said sometimes it is the impacts to the skull that changes it's shape and alters brain function as well. He said where my impacts were, my skull was like a coconut and it should have a little softness like a cantoloup to better allow absorbing impacts better. I frankly never finished treatments. Winter driving is dangerous here and he was expensive.
