Tailbone pain, also called coccydynia or coccygodynia, usually goes away on its own within a few weeks or months. To lessen tailbone pain in the meantime, it might help to:

Sit completely upright with proper posture keeping your back firmly against the chair, knees level with your hips, feet flat on the floor and shoulders relaxed
Lean forward while sitting down
Sit on a doughnut-shaped pillow or wedge (V-shaped) cushion
Apply heat or ice to the affected area
Take over-the-counter pain relievers, such as acetaminophen (Tylenol, others), ibuprofen (Advil, Motrin, others) or aspirin

People stop being dirty minded

Well the obvious thing is think of when it started, and how it might have occured. If it is broken there isnt much you can do let alone a doctor. Its not like you can put a cast on it. Next time you think your going to bruise put ice on 20mins then off 40, repeating until its no longer sore or 12 hours, whichever comes first. Haha ironic, im taking my advanced first aid this week
