Many people often feel nerve pain in the buttocks area due to sitting or inactivity for a long time. This is a precursor to sciatica. Primary sciatica and secondary sciatica cannot be ruled out. You need to find a suitable method to slowly adjust it and clean it in time to prevent the disease from worsening. You should also be careful about inflammation and other hazards. What is sciatica? How many types of sciatica can be divided into? Sciatica ranks first among various neuralgia in the body and is a common disease. But sciatica is just a symptom of the disease, it is not an independent disease itself. The age of onset is usually between 20 and 60 years old, with the most common age being around 40. It is rare before the age of 20 and after the age of 60. Sciatica refers to pain along the sciatic nerve and its distribution area. In other words, pain in the buttocks, back of the thigh, posterior and lateral side of the calf, and outer edge of the foot caused by any reason is called sciatica. Sciatica is divided into two major categories, namely primary sciatica and secondary sciatica, and the causes of the two are different. 1. Primary sciatica Primary sciatica is mainly caused by direct damage to the sciatic nerve due to infection or poisoning, also known as sciatica, which is rare in clinical practice. It often occurs simultaneously with myositis and fibromyositis. Cold and dampness may be the triggering factors. 2. Secondary sciatica Secondary sciatica is pain caused by irritation, compression or damage of the sciatic nerve pathway by lesions in adjacent tissues. Most of the sciatica seen clinically is secondary sciatica. Symptoms: Sciatica often occurs after trauma, physical labor or cold, or recurs due to the above reasons. Most cases present with unilateral pain, but some present with bilateral pain. Typical sciatica presents as pain in one side of the waist and buttocks, radiating to the posterior thigh, posterior and lateral side of the calf, and lateral side of the foot. Walking and changing body position can aggravate the pain, and raising the affected leg is more painful when lying down. |
