No, A subconcussive impact is like hitting your head against a door frame and only having a momentary 'wooh' with no sensation after a second or two.

There was NO G force involved. It was the points that hurt, not the impact.

Many need to focus on neck and head position with pillows. You want to maintain a straight head and neck position. Head lift is not good.

You should spend some time touching your head to desensitize yourself from head touches. You may have trained a concussion like response due to your anxiety. The brain will act like it is concussed if you teach it that head touches are dangerous. So, you need to touch your head or even have somebody else touch your head so you can learn to not respond. A startle response (Don't touch my head.) can cause a false concussion response.
