avulsion The forcible tearing away of a body part by trauma or surgery

chronic A chronic condition is continuous or persistent over an extended period of time. A chronic condition is one that is long-standing, not easily or quickly resolved (tipna.org)

coccygeus muscle One of two muscles in the pelvic diaphragm. A triangular sheet of muscle and tendinous fibers. It acts to draw the coccyx ventrally, helping to support the pelvic floor (see also Levator Ani)

coccyx A small triangular bone at the end of the spinal column

entrapment A disorder of a peripheral nerve characterized by pain and/or loss of function of the nerves as a result of chronic compression. The most common form of entrapment is Carpal Tunnel Syndrome (tipna.org)

epidural Injection of anaesthetic into the space outside the dura mater enveloping the spinalcord

episiotomies Surgical incision into the perineum during the late stages of labour to prevent its laceration during childbirth and to make delivery easier

fascia A sheet or band of fibrous connective tissue enveloping, separating, or binding together muscles, organs, and other soft structures of the body

fibrosis Formation of fibrous tissue

hyperaesthesia A neurologic symptom where there is an unusual increased or altered sensitivity to sensory stimuli

innervation The arrangement or distribution of nerves to an organ or body part

levator ani One of a pair of muscles of the pelvic diaphragm that stretches across the bottom of the pelvic cavity like a hammock, supporting the pelvic organs (see also Coccygeus Muscle)

ligament 1. A band of fibrous tissue connecting bones or cartilages, serving to support and strengthen joints.
2. A double layer of peritoneum extending from one visceral organ to another

nerve block Injection of a local anesthesia to temporarily stop the ability of a nerve to transmit pain signals. The typical anesthetic for PN nerve blocks is lidocaine. PN nerve blocks are an important diagnostic tool.

neuromodulation Electrical stimulation of a peripheral nerve, the spinal cord, or the brain for relief of pain.

Neuralgia (Dictionary.com) – Pain along the course of a nerve. (MedicineNet) Also: A disease, the chief symptom of which is a very acute pain, exacerbating or intermitting, which follows the course of a nervous branch, extends to its ramifications, and seems therefore to be seated in the nerve. It seems to be independent of any structural lesion.

Neuralgia (tipna.org) A subset of neuropathy. Thus the more precise term for pudendal area pain is Neuralgia. PN is therefore best called Pudendal Neuralgia, not Pudendal Neuropathy, as we have been accustomed to doing. Thanks to Pierre Gauvin for this observation

Neuropathy A disease of the nervous system. The three major forms of nerve damage are: peripheral neuropathy, autonomic neuropathy, and mononeuropathy. (Wikipedia) [Need to explain peripheral versus autonomic nerves, how PN is a form of peripheral neuropathy.]

obturator A structure, such as the soft palate, that closes an opening in the body

parturition The process of labor and delivery in the birth of a child

pelvic floor The soft tissues enclosing the pelvic outlet

perineum 1. The pelvic floor and associated structures occupying the pelvic outlet, bounded anteriorly by the pubic symphysis, laterally by the ischial tuberosities, and posteriorly by the coccyx
2. The region between the thighs, bounded in the male by the scrotum and anus and in the female by the vulva and anus

peripheral a. Of the surface or outer part of a body or organ; external
b. Of, relating to, or being part of the peripheral nervous system

piriformis A muscle in the pelvic girdle that is closely associated with the sciatic nerve

prolapse Protrusion of
