Lateral femoral cutaneous neuritis, also known as paresthetic femoral pain, Bernhardt disease, Roth disease, is a disease characterized by sensory abnormalities of the lateral skin of the thigh. The disease is more common in males over 20 to 50 years old with obesity, presenting with numbness on the anterior and lateral side of the thigh, feeling of ants crawling, tingling, burning sensation, coldness, and sweating.

1. What are the causes of the onset of lateral femoral cutaneous neuritis?
First, Etiology
1. Compression of the lateral femoral cutaneous nerve may lead to the disease, such as: spinal deformity, ankylosing spondylitis, spinal bifida, lumbosacralization, pregnancy, pelvic tumor, inguinal hernia, intervertebral disc herniation, etc.
2. Trauma or infection such as: lumbar myositis, pelvic inflammatory disease, neurosyphilis, appendicitis, pregnancy, alcoholism, postherpetic neuralgia, etc. can trigger this disease.
3. Coldness and humidity are common triggers for the disease.
Second, Pathogenesis
1. There may be slight inflammatory cell infiltration around the dermal small blood vessels.
2. The peripheral nerve may swell, there may be perineuritis, inflammatory cell infiltration, and degenerative changes in the nerve.
2. What complications can lateral femoral cutaneous neuritis easily lead to?
The complications of this disease are mainly related to the loss of normal function of nerve lesions. The most common complication is muscle weakness under the control of the nerve, as well as numbness, tingling, and abnormal sensation of the skin. With the long-term loss of nutritional support from the nerve, muscle tissue can produce atrophy. The function of local blood vessels is also controlled by the nerve, so local congestion and redness can occur.
3. What are the typical symptoms of lateral femoral cutaneous neuritis?
Commonly seen in males over 20 to 50 years old with obesity, presenting with numbness on the anterior and lateral side of the thigh, feeling of ants crawling, tingling, burning sensation, coldness, reduced sweating, and a feeling of沉重. Symptoms such as numbness are most common, and the symptoms may worsen with physical labor or prolonged standing, which can be relieved after rest. Physical examination may show varying degrees of hypoesthesia or absence, mainly involving pain and temperature sensation while pressure sensation remains intact. A few patients may have hypopigmentation or hyperpigmentation, and some patients may have slightly thin, slightly dry skin with reduced vellus hair. The disease is usually unilateral, with a few cases involving both sides, a chronic course, with symptoms varying in severity, often taking several months to several years to heal.
4. How to prevent lateral femoral cutaneous neuritis
This disease is usually caused by two common factors: one is traumatic nerve injury, and the other is that local inflammatory reactions involve nerve tissue. Another factor is that there is a space-occupying mass or disc herniation and other lesions that cause nerve compression. Therefore, clinical prevention should be aimed at the cause, be careful in work, and avoid causing trauma. Secondly, for the factors of space-occupying and infectious factors causing the disease, after clarifying the cause, active surgery or anti-infection treatment should be carried out.
5. What kind of laboratory tests should be done for lateral femoral cutaneous neuritis
Patients feel a pricking pain in the skin on the anterior and lateral aspect of the thigh, accompanied by abnormal sensations such as creeping, burning, coldness, and numbness. At the beginning of the disease, the pain is intermittent and gradually becomes persistent, and sometimes the pain can be very severe.
6. Dietary taboos for patients with lateral femoral cutaneous neuritis
The diet of patients with lateral femoral cutaneous neuritis should be light, easy to digest, with an emphasis on eating more vegetables and fruits, and a reasonable diet. Pay attention to adequate nutrition. In addition, patients should also pay attention to avoiding spicy, greasy, and cold foods.
7. Conventional methods of Western medicine for the treatment of lateral femoral cutaneous neuritis
I. Treatment
The cause should be sought and eliminated.
1. Physical therapy includes massage, electrotherapy, heat therapy, magnetotherapy, and ultraviolet light irradiation followed by iontophoresis.
2. Try Vitamin B1, Vitamin B12, and Dibazol.
3. The injection therapy for the lateral femoral cutaneous nerve at the location about 10cm below the anterior superior iliac spine, using a 12-gauge needle to pierce vertically for 3-4cm, then slowly inject 100mg of Vitamin B11 or a mixture of 100mg of Vitamin B11 and 100mg of Vitamin B12, once a day, 5-10 times as a course of treatment. It can also be combined with acupoint injection at Fengchi, Xuehai, and Fufu.
4. If there is stubborn and severe pain, consider nerve section or decompression surgery.
II. Prognosis
Chronic course, varying in severity, often not cured for several months to several years.
