M46.98: Inflammatory spondylopathy, unspecified Sacral and sacrococcygeal region

You have bone inflammation in your sacrum or your coccyx.

The spine consists of several sections. The cervical spine begins below the head. The cervical spine is very mobile. Below that is the thoracic spine. The ribs are attached to the thoracic spine. Below the thoracic spine is the lumbar spine. The lumbar spine is also very mobile and it bears a large part of the body’s weight. After the lumbar spine, the sacrum and coccyx join.

Bone inflammation can be caused by pathogens. The pathogens can get into the bones via small wounds or via the blood vessels. Pathogens may also get into the bone after an operation or after an accident.

Bone inflammation can cause fever and general fatigue. The bones may also be damaged by the inflammation. When bones are damaged their shape can change. Consequently, the shape of the spine can also change.
