I have recently been doing my own research regarding concussions, to be frank I don't trust most physician's opinions, so I have taken it upon myself to independently research.

I have two main topics I am inquiring about, the first is about the actual structural damage to the brain.

If you had two people that suffered literally identical injuries (just thoeretically), and had the same structural damage to the brain, is it possible that one person may experience symptoms while the other does not?

I ask this because I am friends who play football, who do not ever experience concussion symptoms, even when they get hit extremely hard.

Is a person's tendency to experience symptoms, almost like the pain threshold? I have a very high pain threshold. So if someone was cutting me as opposed to a friend, I wouldn't feel as much pain as they do, but the injuries are identical.

Sorry if this seems confusing, basically I am just asking if someone with a less severe brain injury can experience more severe symptoms than someone who does.

Secondly I was wondering about this, "gate," concept.

I have not dramatically increased my blood flow for quite a few months, could the very fact that I have not increased my blood flow be the cause for the symptoms?

Same with noise, I have not been in a noisy area for many months and now I get headaches when I am put in those situations. Could I be experiencing these symptoms due to the fact that I am not used to the noise?




Thanks in advance.
