Coccygeal Nerve Block
A coccygeal nerve block refers to a minimally invasive treatment for chronic lower back and tailbone pain. Several conditions such as herniated discs, compression fractures, spinal stenosis, and sciatica may cause pain in these regions as well as prolonged poor posture or trauma to the coccyx. A rare condition that causes tailbone pain is called coccydynia, but it is not diagnosed very often.
