Coccyx area pain

In the ‘everything is connected to everything’ approach we can see that low-back pain, hip pain, and head pain may arise in those suffering an anterior displaced and/or side bent coccyx. Filum Terminale is a long slender connective tissue strand that terminates at the end of the spinal cord. The upper part, or filum terminale internum, reaches as far as the lower border of the second sacral vertebra. The lower part, or filum terminale externum, extends downward from the apex of the tubular sheath and is attached to the back of the first segment of the coccyx in a structure sometimes referred to as the coccygeal ligament. As the sacrococcygeal ligaments anteriorly flex the coccyx, it also compresses and overstretches the sensitive filum terminale. Some manual therapists believe that when a coccyx moves anterior, it tugs on the dural membrane via the filum terminale. This, in turn, is believed to cause dural drag, loss of cerebrospinal fluid flow, and resultant Central Nervous System irritation.
