Pudendal nerve entrapment is an example of nerve compression syndrome. Pudendal neuralgia (PN) refers to neuropathic pain along the course of the pudendal nerve and in its distribution. This term is often used interchangeably with pudendal nerve entrapment. However, it has been suggested that the presence of symptoms of pudendal neuralgia alone ...
The pudendal nerve is the main nerve of the perineum. [1]: 274 It is a mixed (motor and sensory) nerve and also conveys sympathetic autonomic fibers.It carries sensation from the external genitalia of both sexes and the skin around the anus and perineum, as well as the motor supply to various pelvic muscles, including the male or female external urethral sphincter and the external anal sphincter.
The timing/duration of symptoms may be continuous, intermittent, and/or positional. This is dependent on the underlying cause of entrapment and the specific nerves involved. For example, pain while sitting is associated with inferior cluneal nerve entrapment, pudendal nerve entrapment, and anococcyeal nerve entrapment. [11] [12] [13]
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Damage to the defecation centre within the medulla oblongata of the brain can lead to bowel dysfunction. A stroke or acquired brain injury may lead to damage to this centre in the brain. Damage to the defecation centre can lead to a loss of coordination between rectal and anal contractions and also a loss of awareness of the need to defecate. [12]
The pudendal nerve may sustain irreversible injury if it is stretched more than 12% of its original length. [15] [16] The nerve is especially vulnerable to stretch damage during childbirth because of the course of the nerve, [17] as it runs in close proximity to pelvic muscles (piriformis and coccygeus) and ligaments, before exiting and then re ...
Pain extending outside of the vulvar vestibule may have other sources. Damage to the pudendal nerve ("pudendal neuralgia" or pudendal nerve entrapment) can cause unilateral or bilateral pain. Persistent genital arousal disorder can also cause pain in the vulvar vestibule. Spinal pathology can also cause vulvar pain. [10]
In one study of 68 people with proctalgia fugax, 55 had tenderness along the course of the pudendal nerve. Pudendal nerve block relieved symptoms completely in 65% of the participants and reduced symptoms in 25%. This suggests that a major cause of proctalgia fugax may be pudendal neuralgia. [8]
