Hi i was the same i had mine 3 weeks ago and she puts in the local first which stings a little then i didnt feel the actual needle at all. Just a slight pressure but not really noticable lol.
Then its over in about 10min all up. i had to stay there on the bed for 2hrs and then i could go home i had to rest for 24hrs. Its just to make sure the small hole seals up nice and it would do very quick as the needle is very thin.
So i just layed on the couch for the day and i was fine to do normal things after 24 hrs. Within reason.
Good luck and dont stress the procedure is no where near as bad as people think i was pleasantly surprised.
Oh its just the waiting for results that is the worst.
