Why does my tailbone hurt when sitting?
Tailbone pain — pain that occurs in or around the bony structure at the bottom of the spine (coccyx) — can be caused by trauma to the coccyx during a fall, prolonged sitting on a hard or narrow surface, degenerative joint changes, or vaginal childbirth.
How do you tell if your back pain is muscular or skeletal?
If the pain you feel extends to your arms, forearms, and hands, the source may be your cervical spine. On the other hand, if you feel the pain radiating to your legs, it may be a problem with the lumbar spine.
How many bones are in the lower back?

What are the lower back bones?
The bones of the pelvis and lower back work together to support the body’s weight, anchor the abdominal and hip muscles, and protect the delicate vital organs of the vertebral and abdominopelvic cavities. The vertebral column of the lower back includes the five lumbar vertebrae, the sacrum, and the coccyx.
What muscles are in your lower back?
Middle trapezius
Your lower back consists of five vertebrae. Discs between them cushion the bones, ligaments hold the vertebrae in place, and tendons attach muscles to the spinal column. The lower back has 31 nerves. As well, organs such as the kidneys, pancreas, colon, and uterus are located near your lower back.
