Tailbone pain is frustrating, and is often caused by a combination of poor posture and sitting in the wrong types of chairs for long periods. But proper posture can help to minimize discomfort. Sit with your back against your chair with your feet flat on the floor. This helps to take the pressure and weight off of your tailbone. Likewise, when you sit down, lean forward as you take your seat. And you can also invest in a supportive coccyx pillow insert with a u-shaped cutout to help support your tailbone and minimize pressure and discomfort.
