Lumbar intervertebral disc protrudes into the spinal canal, which is a typical sciatica. When it comes into contact with nerve, it produces compression, causing pain in buttocks, thighs and calves. Sciatica is not real sciatica, but radiation leg pain from hip to thigh and calf. The treatment of sciatica is as follows: more than 90% can be relieved by conservative treatment, such as taking medicine, resting and less activity; If the pain lasts for more than 3 months and the symptoms are serious, such as insomnia at night, it is an indication of surgery and requires surgical treatment. If there is a bowel movement disorder or foot drop, the ankle can't be lifted. This is the absolute indication of surgery, and emergency surgery is necessary.

Pear muscle is the smaller muscle in gluteal muscle, which is located in the middle of gluteal muscle area. Piriform muscle syndrome is caused by the injury and inflammation of piriformis muscle, which makes sciatic nerve, other sacral plexus nerves and hip blood vessels passing through this hole be pulled, stimulated or compressed by sciatic nerve. It usually happens in people who are sedentary, squatting for a long time, need weight-bearing training, and have a cold. Traditional Chinese medicine believes that piriformis syndrome is a category of arthralgia syndrome, which is caused by pathogenic factors such as wind, cold and damp heat, blockage or congestion of meridians, and obstruction of qi and blood. Most piriformis injuries are caused by external forces, such as sprain, crossing and repeated squatting. Especially in abduction of lower limbs, when squatting upright, piriformis muscle will be stretched for too long and damaged; Injection of drugs denatures piriformis muscle and causes fiber contracture. Fracture and displacement of posterior upper acetabulum. Inflammatory injury of piriformis muscle can also occur when hip and waist are infected.

Keep lying flat and slowly lift one leg. When the elevation angle is less than 60 degrees, there is obvious pain, which means positive. If the angle is higher than 60 degrees, the pain will be relieved and it can be judged as piriformis syndrome. When piriformis syndrome occurs, local massage is usually used to relieve pain, improve blood circulation of local muscles, reduce nerve compression and help repair damaged tissues. I like ballet very much. I have been dancing for 7-8 years, and I usually do a lot of exercise when dancing. So there are often some mild leg pain symptoms, which I attribute to excessive exercise. But suddenly one day, it felt different. I remember that day very clearly. I feel very weak when I exercise, and I feel very tired when I get home, and my calves are swollen. Then the next day, the left lateral hip and the left leg and calf began to swell.

At that time, I didn't realize the problem of lumbar disc herniation, but in retrospect, if I hadn't always blamed some pain in my body on excessive exercise, maybe I could have paid attention to the problem of leg swelling and leg pain earlier. My symptoms will get worse soon. Getting up every day will involve the pain on the outside of the left buttock, and it is still unbearable pain, but lying down can relieve the pain. So, I must stay in bed. Stay in bed 19 days or so, and feel the pain relieved: you can get out of bed 10 minutes. After only 10 minutes, the left leg will be sore and swollen. Although the pain is tolerable, the symptoms will be more serious after long-term activities. It is impossible to walk and stand normally. Standing for 2~3 minutes will cause leg pain and radiate to the buttocks. This has seriously affected my normal life.
