Hi Dean,
Try to remember that you've felt this way in the past and you actually were fine afterwards and didn't have another concussion.

I recently read an article from the Queensland University Brain Institute. (State in Au where I live). It was about concussions and body hits in Rugby Union. Yes, they can happen and need to be considered but you're not playing Rugby Union.

They stated that it would take a a very large amount of force to create a situation where there was enough acceleration or deceleration of the brain inside the skull to cause a concussion if the head wasn't hit. It's more likely that your chest would have absorbed the force of the energy from what you describe.

Mark in Idaho posted this to you on one of your other threads when you asked a similar question. https://www.neurotalk.org/1300372-post15.html
