I'm getting my wisdom teeth out in a week. The bottom two will be pulled the top will be cut. I'm gonna have to get a total of 10 shots.?

The oral surgeon told me I'm getting 1 in each cheek 2 in the roof of my mouth a 1 in all four areas of the gum. He said a total of 8-10 shots. My main concern is the pain of the shots. Can anyone tell me If it's going to be really painful? I'm going to be getting nitrous (laughing gas) before and during the surgery. The only part I'm afraid of is the shots. I've never had to have any dental work done accept cleanings.
