Hello,

This is going to be an "annoying" question, so bear with me.

Ever since my second concussion, I've had anxiety about even small things hitting my head. Sometimes I get symptoms from these things but I'm not sure how to know if it's a concussion. I no longer have daily concussion headaches so when I get headaches now, I notice. I am writing this to help put my anxiety to rest.

Would any of the following cause a concussion, or just anxiety? (all of these things were accidental of course)

-grabbing your nose, and jolting your head to the side with it (I was wiping my nose)
-poking yourself hard in the head while grooming/washing
-missing a bottom step on the stairs and landing hard on your feet (no head impact, just sort of thudding hard on your feet)
-going over large potholes in the car
-being slapped on the back

that's all I can think of for now, but I know there's more.

I guess my question is, how hard do you have to hit your head to get a concussion? My first two were obvious - heavy doors/doorways hitting my head.


Thank you for your honesty and patience.
