In sm pain 🤕🤕

I have had a really painful tailbone for the last 2 days. I don’t remover hitting it or doing anything to injure it but I’ve been unable to sit or lay comfortably. I had been worst in the last hour or so and I just went to the bathroom and their is blood all over my upper butt and lower back, I’m not on my period but I don’t understand why it is bleeding and why it hurts so bad! 😫 also if you know how to stop this from happening pls comment!!
