The causes of coccydynia are multifactorial. They include:
- Falls: A bad fall can bruise, break (fracture) or dislocate your tailbone.
- Repetitive strain injuries (RSI): Sports like bicycling and rowing require you to lean back and forth. Too much of that repeated motion can strain the tissues around your tailbone.
- Pregnancy or childbirth: During the third trimester of pregnancy, your body secretes hormones that soften the area between your tailbone and sacrum. This gives your tailbone more flexibility during childbirth. It’s a natural process. But in some cases, this can stretch the muscles and ligaments around your tailbone too far, causing additional pain.
- Carrying extra weight: Extra weight places additional pressure on your tailbone.
