The coccygeal plexus gives rise to the anococcygeal nerve. [2] The coccygeal plexus is distributed to the coccygeus muscle, part of the levator ani muscle, the sacrococcygeal symphysis, and (via the anococcygeal nerve) a small area of skin between the tip of the coccyx, and the anus. [1]
In a radiculopathy, the problem occurs at or near the root of the nerve, shortly after its exit from the spinal cord. However, the pain or other symptoms often radiate to the part of the body served by that nerve. For example, a nerve root impingement in the neck can produce pain and weakness in the forearm.
A pudendal nerve block will temporarily remove or reduce the pain, although it is not considered diagnostic on its own because many other disease processes apart from entrapment can cause pain in the anatomic region of the pudendal nerve. [33] Infiltration is usually near the ischial spine. [31]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
It may be classified as neck pain (cervical), middle back pain (thoracic), lower back pain (lumbar) or coccydynia (tailbone or sacral pain) based on the segment affected. [1] The lumbar area is the most common area affected. [ 2 ]
The cauda equina (from Latin tail of horse) is a bundle of spinal nerves and spinal nerve rootlets, consisting of the second through fifth lumbar nerve pairs, the first through fifth sacral nerve pairs, and the coccygeal nerve, all of which arise from the lumbar enlargement and the conus medullaris of the spinal cord.
Last summer Len Barchanowicz, 45, experienced sharp pangs in his neck that felt like a pinched nerve. After about a week, his symptoms intensified and he experienced chest pain and trouble ...
The name coccyx is derived from the Greek word for 'cuckoo' due to its beak-like appearance. The coccyx itself is made up of three to five vertebrae, some of which may be fused together. The ventral side of the coccyx is slightly concave whereas the dorsal aspect is slightly convex.
