Tailbone pain is a common pregnancy complaint. According to The Bump, increased hormones relax the ligaments, which cause a shifting of bones in the pelvis and results in discomfort. A growing baby and expanding uterus also push against the tailbone, which can be another cause of pain.
The Bump advises that the best way to alleviate tailbone pain is to take pressure off the tailbone. Alternating between sitting and standing or using a donut pillow can help. Yoga and stretching also help to ease discomfort. Pamper Yourself Denver suggests substituting a birth ball for a chair. If these methods fail to relieve discomfort, it is important to inform a doctor of any existing tailbone pain.
