If you’re far into your pregnancy (in your last trimester), it shouldn’t come as a surprise that you may experience muscle pain or aches near your tailbone and pelvis. The ligaments around the tailbone become more loose at this stage in your pregnancy to accommodate the baby. However, they may feel sore or like muscle pain as your body changes. But if the pain feels unusual, get it checked out by your doctor.
Bad posture is also a common cause of muscle pain near your tailbone. It can place pressure on the spine and coccyx. Consequently, your muscles or tendons may come under stress. They become tight and strained, leading to muscle pain and discomfort.
If you’ve recently injured your mid or low back, muscle pain near your tailbone may arise. Imbalances occur causing tenderness and discomfort in and around the spine and low spine areas. In particular, a gluteus maximus injury or muscle strain may cause pain near the tailbone. The gluteus maximus attaches to the tailbone (coccyx) and may pull or become tightened when injured or aggravated. If you are experiencing another type of bone pain, check out our article here.
