actually i just got my flu shot last week. i waited in the waiting room for about 20 mins they finally called my name took me back didnt even have me sit down jus put the needle in and took it out and said i was done. i swear to you i did not even feel it go in. youll be fine! i had to look at the needleto make sure she didnt forget to inject it. so the total time in the drs office...22 mins.
