Hi Ben, I am not aware that I said any of that and especially in those words.
In fact I specifically tried to avoid one of those words. I am not there looking at you as we're on the internet, but if I was in the same situation I would doubt I had sustained a new brain injury although a whiplash could cause problems obviously.

You need to treat the symptoms from your neck and I imagine you did all that with ice etc.? It's probably going on two weeks now so if your neck or shoulder is still sore and you still feel a bit "off", then you should check with your doctor.

Yeah, unfortunately I can't help you with the physics regarding forces needed to sustain serious injury from a whiplash. I've seen many posts about it over the years here. I just know if something hurts then it hurts and if it hurts a lot then I probably need it checked. I have terrible problems with my neck and spine and I do know that if I injure my neck or back working in the yard or something, then it can really make me feel very ill. It's a pain and feeling that is hard to describe. If you feel you have a whiplash injury or even more subtle injury you need to get it looked into.

Feel better soon.
