I realize it's a much different point of view when there's adrenaline and anxiety. I'd imagine a lot of us enjoy the placebo of reassurance given how wishy washy doctor visits can be. And concussive forces can be pretty tough to gauge or really set in reality at times. My worst concussion of the last decade was an assault from a woman who at the time weighed about 25-30 lbs less than me and I could barely tolerate lights and had trouble driving at night for nearly a month, in addition to absolutely brutal daily headaches. And that was just from a single hammer fist strike (closed fist) to the top/side of my head.
