Patient: Description of condition (onset, main symptoms, hospital visited, etc.): The disease has been present for 20 years, and I had surgery at China-Japan Friendship Hospital in 2001. But now it is recurring. When I walk about 300 meters, I get numbness in my feet, then up to my legs, and my legs hurt. Last year, I took medicine at the Jishuitan Hospital, but the effect was not very obvious. We did not agree. Some days ago, I had 10 sessions of closed triple therapy at the Gitan Hospital of Traditional Chinese Medicine with no effect. Now I would like to have Chinese medicine treatment with you and get your help. The difference between the two is that the latter may be relieved in treatment and in the short term after treatment, and the symptoms may recur after cold, sedentary, exertion, or heavy lifting, while the former has a more definite effect. The former treatment effect is more accurate, but you belong to 2 times surgery, which can be called revision surgery, the effect may be discounted, but it varies from person to person. You can bring your medical records to our clinic for consultation
