Sensory abnormal sciatic pain

　　Abnormal sciatic pain is caused by the lateral cutaneous nerve of the thigh, which originates from the 2nd to 3rd lumbar nerves, passes through the lateral border of the psoas major muscle, obliquely across the iliac muscle, along the pelvis through the deep surface of the inguinal ligament, and exits the fascia lata at 10cm below the anterior superior iliac spine to reach the skin of the thigh. During the course of the nerve, if the lateral cutaneous nerve of the thigh is affected due to compression, trauma, infection, or other reasons, it may lead to this disease.

　　1. Compression of the lateral cutaneous nerve of the thigh

　　Compression of the lateral cutaneous nerve of the thigh, such as vertebral deformity, spondylitis, spondylolysis, lumbosacralization, pregnancy, pelvic tumor, inguinal hernia, intervertebral disc herniation, etc., can lead to this condition.

　　2. Trauma or infection

　　Trauma or infection such as lumbar muscle inflammation, pelvic inflammation, neurosyphilis, appendicitis, pregnancy, alcoholism, postherpetic neuralgia, etc. can trigger this condition.

　　3. Coldness and humidity

　　Coldness and humidity are also common triggers for this condition.

　　Abnormal sciatic pain does not have special complications, mainly local sensory abnormalities or mild dysfunction, caused by pressure or trauma leading to sensory abnormalities or pain in the distribution area, local hyperesthesia or impairment. It often presents as a chronic course, more common in males than in females, with a ratio of about 3:1, and often occurs on one side. Symptoms include abnormal sensation on the outer side of the thigh, such as a feeling of ants crawling, burning sensation, numbness, or pricking, or local hyperesthesia or loss of sensation.

　　Patients with abnormal sciatic pain are more common in males than in females, with a ratio of about 3:1, and it often occurs on one side. The symptoms include abnormal sensation on the outer side of the thigh, such as a feeling of ants crawling, burning sensation, numbness, or pricking, or local hyperesthesia or loss of sensation. The lateral cutaneous nerve of the thigh originates from the second to third lumbar nerves, passes through the lateral border of the psoas muscle, crosses the iliac muscle diagonally, along the pelvis through the deep surface of the inguinal ligament, and exits the fascia lata 10 centimeters below the anterior superior iliac spine to the skin of the thigh. If the lateral cutaneous nerve of the thigh is affected due to pressure, trauma, or other reasons during its course, sensory abnormality sciatic pain may occur. It is more common in middle-aged and young males with obesity. The main symptoms are sensory disorders on the anterior and outer side of the thigh, especially in the lower two-thirds of the outer side of the thigh. Symptoms include numbness, a feeling of ants crawling, piercing pain, burning sensation, and a feeling of weight, which may worsen after physical labor, prolonged standing, or walking, and may alleviate after rest. During examination, there may be varying degrees of superficial sensory disorders, mainly pain, temperature, and tactile sensation impairment or loss. The skin at the affected area is slightly thin, but there is no muscle atrophy or motor impairment. The histamine test and pilocarpine sweating test are normal. This condition often persists for many years, with symptoms varying in severity.

　　Abnormal sciatic pain severely affects the daily life of patients, so it should be prevented actively. However, there is currently no effective preventive method for this condition, so early detection and early treatment are of great significance for the treatment of the disease.

　　Abnormal sciatic pain can be diagnosed through a comprehensive physical examination, including a medical history, pathological examination, and comprehensive analysis such as nerve fiber staining and acid-fast bacillus detection. Weight loss in obese individuals may alleviate or eliminate symptoms. Vitamin B complex drugs can be used. Severe pain can be treated with oral analgesics, sedatives, or carbamazepine, with 100mg of Vitamin B1 and 10mg of 654-2 injected, or 5-10ml of 2% procaine can be used for nerve block at the point where the nerve exits the fascia lata, which may be effective. Other treatments such as physical therapy, acupuncture, and massage can also be tried.

　　Patients with sensory abnormality of the sciatic pain should eat rich in lipids, vitamins, and proteins. Avoid greasy, cold foods, spicy and刺激性 foods, and overly nourishing tonics..

　　1. Egg yolk

　　The main component of egg yolk is lecithin, which has a nutritional effect on nerves. 2-3 eggs per day are enough.

　　2. Tomato

　　Rich in vitamin B and vitamin C. It has the effect of nourishing nerves and clearing free radicals. It has a good auxiliary repair effect on patients with nervous system diseases. 200g per day is sufficient.

　　3. Cucumber

　　Mainly contains vitamin B1, which has a good nutritional effect on nerves. It is recommended to consume about 100g per day.

　　4. Milk

　　High in protein content and calcium, which has a stabilizing effect on nerve function. Calcium also has the effect of anti-allergy. It is recommended to drink about 500 milliliters per day.

　　The main treatment for sensory abnormality of the sciatic pain is to actively find the cause and. to eradicate it.Severe cases can be treated with peroneal cutaneous nerve injection therapy, or. ProcaineLocal block..

　　1. Physical therapy:Including massage, electrotherapy, heat therapy, magnetotherapy, and ultraviolet light irradiation followed by iontophoresis, etc.

　　2. Drug treatment:Vitamins B1, B12, and Dibazol can be tried.

　　3. Peroneal cutaneous nerve injection therapy:About 10cm below the anterior superior iliac spine, at the location of the sartorius muscle, insert a 12-gauge needle vertically for 3-4cm and slowly inject a mixture of 100mg of Vitamin B11 or 100mg of Vitamin B12, 1 time/d, 5-10 times as a course of treatment. It can also be combined with injection at the acupoints of Fengchi, Xuehai, and Futu.

　　If there is stubborn and severe pain, consider nerve section or release surgery.
