Supragluteal neuritis is caused by injury to the supragluteal nerve, resulting in severe pain in the lower back and buttocks. In Chinese medicine, it belongs to the category of “tendon out of groove”. It is one of the common clinical back and leg pains, and the main symptom is pain in the lower back and buttocks. The pain is dull, aching or stabbing, and radiates to the lower hip and thigh on the affected side, but mostly not over the knee. The pain is aggravated by bending, turning, squatting and standing. Previously, I have introduced sciatica, lumbar strain, acute lumbar sprain, gluteal fasciitis, lateral femoral dermatome neuritis and other causes of lumbar pain, so for the sake of differentiation, here is another explanation of supragluteal dermatome neuritis. The superior gluteal cutaneous nerve is a sensory nerve, a group of cutaneous branches emanating from the lateral branch of the posterior branch of the lumbar 1, 2, and 3 spinal nerves, distributed in the upper part of the skin of the buttocks. Since each branch crosses the thick lumbar musculature and lumbar dorsal fascia during its journey, and crosses the hard iliac crest before reaching the upper buttocks, the superior gluteal nerve is vulnerable to injury. Modern research has confirmed that the chemical substances produced by the aseptic inflammatory reaction of soft tissues stimulate the nerve endings and cause pain, reflexively cause muscle spasm and small vessel spasm, insufficient blood supply to soft tissues, metabolic and nutritional disorders occur, and the inflammatory reaction becomes inflammatory adhesions or inflammatory fibrous tissue hyperplasia, and the contracted and degenerated soft tissues produce “embedded pressure” on small vessels and nerve endings. The contracted and degenerated soft tissues produce an “embedded pressure” on small blood vessels and nerve terminals. Therefore, when acute and chronic injury occurs to the soft tissues of the lumbar region, the superior gluteal nerve is often involved. When the nerve is injured, it can cause congestion, edema and even bleeding in the nerve and its surrounding soft tissues, which can lead to degenerative reaction of the nerve and thickening of the nerve bundle in the shape of a pike, resulting in neuralgia symptoms. Therefore, acute and chronic muscle strain, myofasciitis, degenerative lesions of the lumbar spine, and inflammation of the sacroiliac and hip joints in the lumbar and hip areas are all causative factors for epiglottic neuritis. The clinical manifestations of epiglottic neuritis are pain in the affected lumbar hip area, which is stabbing and tear-like, and there may be radiating pain in the posterior thigh, but the pain does not exceed the knee joint. In the acute stage, the pain is more intense, bending is limited, it is difficult to get up and sit, and when changing from sitting to standing, it is necessary to climb and support others or objects. This is the outlet of the superior gluteal nerve, which is one of the bases for the diagnosis of this disease. This is the exit point of the superior gluteal nerve, which is one of the criteria for diagnosing the disease. The straight leg raise test is positive, but no nerve root symptoms appear. The upper part of the buttock may be hypersensitive or dull on examination. Epiglottic neuritis is easily confused with gluteal fasciitis. But in gluteal fasciitis, the pain is mainly soreness; gluteal fasciitis also has pressure pain in the buttocks, but the pressure pain is more widespread, unlike epiglottic neuritis where the pressure pain is limited; gluteal fasciitis does not have sensory hypersensitivity or dullness in the upper part of the buttocks. Secondly, it should be distinguished from sciatica. Sciatica pain often radiates to the calf and dorsum of the foot; sciatica has symptoms of nerve root irritation, such as coughing that can cause leg pain; sciatica often has abnormal tendon reflexes and altered sensation in the nerve distribution area. It should also be differentiated from lateral femoral cutaneous neuralgia. The pain of lateral femoral dermatomal neuralgia is often on the lateral side of the thigh, not over the knee; on examination there is hypersensitivity or dullness of sensation on the lateral side of the thigh. Finally, it should be distinguished from chronic lumbar strain. Patients often have a history of lumbar muscle strain, such as prolonged standing and heavy lifting; patients have predominantly low back pain that decreases with activity and worsens with exertion; patients may have pain in the buttocks, but it rarely radiates to the thighs. Clinical low back pain is so varied that sometimes it is easy to talk about it and difficult to see it. Some patients with gluteal fasciitis have only low back pain and no hip pain; some patients with supragluteal dermatomal neuritis and no sensory hypersensitivity and dullness in the hip; some patients with lateral femoral dermatomal neuritis have only pain at the knee joint, etc. As a patient there is no way to know what kind of back and leg pain you are suffering from and you have to go to the doctor. Therefore the clinical experience of the doctor plays a very big role in diagnosing patients with atypical low back and leg pain. In the early stage of injury, the pathological changes can be reversible and the application of conservative treatment, such as acupuncture, massage, and closure, can be effective. In the late stage, when the lesion is irreversible, the above conservative treatment is often not effective and surgical means, i.e. soft tissue release, must be used to completely eliminate the source of the disease and cure it.
