Did i break my tail bone?

I was skipping with my friend, and we both sliped and fell, but we were like peeing our selfs laughing, so it didn't hurt, but its been 4 weeks and my tail bone still hurts. Is still brused, its like red, black and green, did I break it? Like when I sit down it doesn't hurt, but when its time to get up, it hurts so bad I cry. Like it feels some one is hitting it over and over again, it also feels like that when I bend to get something or if I sit criss cross on the floor. I don't want to go to a doctor because who wants someone looking at there butt lol but please help. I hurts bad and is my 4th week into this.
