‘Piriformis syndrome’: Controversial syndrome.Theoretically, it is sciatic nerve compression by the piriformis muscle at the level of the sciatic notch.Symptoms include buttock and posterior thigh pain that is reproduced with maneuvers that stretch the sciatic nerve.No objective clinical, electrodiagnostic, or imaging evidence of nerve injury.

Also known as deep gluteal pain, piriformis syndrome is a pathological condition diagnosed by ruling out other causes and is hypothesised to be due to muscle spasms or compression by piriform muscle, fibrous bands, vascular malformations and adherences to the obturator muscles and the quadratus femoris muscle. It manifests as pain in the gluteal region, with or without accompanying sciatic pain. It worsens with local deep pressure and generally continues for years.
Hip Pain
Benjamin Apichai in Chinese Medicine for Lower Body Pain, 2021
Piriformis syndrome usually starts with tenderness, shooting, electrical sensation, tingling, or numbness in the buttocks, usually on one side only. Pain can be severe and extend down the length of the sciatic nerve.10
Possibilities of kinesio taping to prevent injuries of professional dancers
Published in International Journal of Occupational Safety and Ergonomics, 2019
KT was also effective in eliminating sacroiliac joint pain of recreational dancers, occurring in 13–25% of patients in the dance population [43]. Dancers and jumpers also often suffer from so-called jumper's knee. Jumpers using kinesio tape experienced significant reduction of knee pain on landing from countermovement jumps, increasing knee flexion during the decline squat and on landing from a countermovement jump [44]. Besides, dancers may suffer from piriformis syndrome caused by irritation of the sciatic nerve due to spasm of the piriformis muscle. The 72-h KT applied on the piriformis muscle trigger points relaxed the tensed muscle and significantly reduced pain syndrome in 33 patients [45].
A rare cause of sciatica discovered during digital rectal examination: case report of an intrapelvic sciatic notch schwannoma

Common causes for non-discogenic sciatica include piriformis syndrome, distal foraminal nerve root entrapment and ischial tunnel syndrome. Neurogenic tumors presenting with sciatica are rare. Most schwannomas of the lower extremity arise from the posterior tibial nerve at the tarsal sinus usually presenting as a painful palpable mass and seldom arise from a more proximal sciatic nerve location.1 Extraspinal schwannomas develop in adults between 20 to 50 years of age with no sexual predominance.1 The lesions are often solitary and are at low risk for malignant transformation.
An overlooked nerve in neuropathies associated with intragluteal injections: the posterior femoral cutaneous nerve
Published in Postgraduate Medicine, 2022
Moreover, in the current study, the BMI was found to be lower in patients with PFCN lesions. In addition, as considered in piriformis syndrome, vasotoxicity, and perivascular edema due to injection in the inferior gluteal vein located in the near proximity of both nerves in the piriformis muscle inferior can contribute to the process of neuritis in both nerves [18]. The late onset of neurological deficits and presence of axonal damage in the current study patients with PFCN lesions suggest that there could be chemical and vascular neuritis rather than direct nerve injury.
