See a doctor. Fracture, contusion, hematoma are all possibilities...
You . You may have a sprain or fracture of your coccyx (tailbone). You should be evaluated by your doctor right away. An x-ray will likely be ordered. In the meantime try not to sit down for too long or lay flat on your back. If you need to sit use a doughnut shaped pillow. Also anti-inflammatory medications like advil (ibuprofen) or Motrin can help. Also an over the counter stool softener can be used if it hurts to have a bowel movement. I hope you are better soon.
