Flu shot 11/12/20

I hate needles. The smell of the alcohol swabs then a presence of a nurse hand. There is pain and the knowing of a object going through your skin and injected with some type of medicine components .Havent gotta flu shot since 2006. My grandpa had cancer surgery and my mother made us get it since he was weak and getting shot for a precaution. This time it's still my mom that made me and the reason which is covid 19. Which I dont think it is associated with. But I got and 10 hours later I still have pain but hopefully it's gone soon.
