Back again with another nervous question

A week ago I bumped my head while helping my friend shoot a video. I was holding the (large, kind of heavy, maybe 2-3 lbs, 5 at most) camera close to my head, and momentarily forgot that the small view screen was extended. I bumped the screen into my ear, and it kind of hurt. Started to panic internally. I was already feeling pretty poorly when the impact occurred so it was hard to tell if it made it any immediate difference. I Haven't felt very good at all ever since that day

I'm really freaked out that I've given myself a new concussion. My symptoms have been especially bad today. I hate bumping my head (

my neurologist looked at my eyes and balance a few days after the impact and said she doesn't believe it caused any damage (not enough force/momentum) and that our skulls are designed to protect against minor impacts like this. For what it's worth, several weeeks ago I lightly bumped heads with someone and that turned out fine. This felt a liiiittle stinger of an impact though.

but I'm still freaked out. I guess she has a point, as my skull did not reslly move or whip or anything, and thr camera was close to my head. Is there merit to this? Your head/neck would have to move and cause your brain slide into the skull to be injured, right? Or does it not matter? I'm Scared to death
