Coccydynia, or tailbone pain, can be a gradual aching or a severe pain near the base of your spine. When you get up, have sex, or go to the restroom, it may hurt. In a few weeks or months, it normally fades away on its own.
The origin is often unclear, but frequent causes include falls, infections after delivery, and sitting for too long on a hard surface. Cancer may be the cause of tailbone discomfort, albeit this is an uncommon occurrence. It might be bone cancer or another sort of cancer that has spread to your bones, known as metastatic cancer.
If your aches don't go away, regardless of the cause, consult your doctor. The sooner you figure out what’s causing the problem, the sooner you can treat it and start to feel better.
