Where is my Coccyx?
The coccyx is the anatomical term used for tailbone which is the bone at the very bottom of your spine, so in your buttock region. The pelvic floor muscles as well the gluteus maximus muscle have attachments into the bone. There are also numerous fibrous ligamentous attachments in this area as well to the sacrum which help hold the bones together and keep them stable.
What causes pain in this region?
Pain in the tailbone region may be referred to as coccydynia and is most commonly is caused by a traumatic event. For example a fall onto the backside or during childbirth. This can cause bony bruising or a fracture of the bone. It can also cause inflammation which can lead to pain and discomfort. Other causes can be degeneration or wear and tear of the joint which links the coccyx to the sacrum or possibly other surrounding joints which can be often overlooked. Instability i.e excess or poorly controlled movement in the joint can also cause sensitivity and pain in the area. Pain in this area may also be referred pain from tight muscles containing trigger points for example the buttock or pelvic floor muscles. 'Sciatica' can also cause pain the tailbone region. In rare cases pain in the coccyx area can be due to tumors and infections.
