If you think about all the other factors you mentioned...

Impacted wisdom tooth (ouch)
local anaesthesia
stress
no food
no caffeine (the fact you mentioned it makes me think you would normally have coffee or tea for breakfast)

... it's any wonder you're not feeling great. Having an impacted wisdom tooth removed is no walk in the park. It's normal to feel sore and get a headache or feel a little funny as you say.

The pressure the dentist used would probably have impacted your jaw more than your skull. I honestly doubt that the way you are feeling post op is anything to do with your skull changing shape.

I can't remember it ever taking a day and a half for the numbness to wear off from the anaesthetic. That seems a very long time, but it just could be that I've forgotten.

Please don't think of yourself as an hypochondriac. We're all here for support and information and we're not here to judge you or think of you as an hypochondriac for having the concerns that you have.

If you want, you could even ask on our Dental Forum. I'm sure Bryanna would be happy to ease your mind about these things too.

I actually would be more concerned about my jaw and the nerves around my jaw than my skull... but that's just me.

My experience was not "deforming the skull," but direct pressure that caused brain trauma/mTBI symptoms. Yes, pressure on our skulls can do damage. Mine was over an old concussion, however.

How does it cause trauma to the brain if the skull is not strained?

Well, I guess I find it more helpful (for me) to focus on what symptoms I am dealing with and how to manage them. I am sorry you were injured. But for me, Whether my skull was strained or not is not really going to help with treatment for the trauma. Yes, direct repeated pressure from a hair stylist's aggressive (brutal) head massage caused me a lot of symptoms (3 months ago now). Thank god I have improved. Still not 100%, may never be.

The brain moves inside the skull. It can actually bounce from front to back (coup-contra-coup). Shaking or vibrating can strain the brain. An impact is often over in a very short time period. Shaking or vibrating can last much longer. Either one can cause damage.

I don't think a simple pressure like the dentist did can cause a problem. There are other causes at play in this situation.
