On the one hand, be an attentive person who records pain. You should carefully observe and summarize the location of the pain (where it hurts most, whether it radiates to any part of the body), its nature (whether it is a sharp pain like a knife cut, a dull, sore, swollen pain, or a pain like an electric shock), the time and pattern of the attack (how long has the pain lasted, whether it is continuous or intermittent, and if it is intermittent, whether it is daytime or nighttime pain, and how long the pain lasts), and the factors that affect the pain (how did the pain start? (how the pain started, under what circumstances the pain will worsen and under what circumstances the pain will decrease), and what treatment you are currently receiving (including what medications you are taking and how effective they are), etc. On the other hand, you should follow the doctor’s instructions and bring your medical records and previous test results, especially the imaging films, to the follow-up appointment. 3.Does the injection mean “closed”? Closed treatment is the former Soviet Union physician invented, the use of high concentrations of local anesthetics and high doses of hormones to temporarily “closed” a treatment method of pain transmission, has long been eliminated. Our current injectable treatment uses very low concentrations of local anesthetics and safe doses of glucocorticosteroids, and a more precise injection technique that reduces the amount of fluid used, thus significantly reducing the associated side effects. In addition, depending on the patient’s condition, we may also inject other drugs such as medical ozone, sodium hyaluronate, etc., which are not compatible with “closure”. Therefore, the modern treatment method is called “injection therapy”, rather than playing “closed”. 4, injection therapy can “go to the root of the disease”? This question cannot be generalized. For most soft tissue-derived pain, injection therapy can play the role of eliminating inflammation, improving local blood flow, and breaking the vicious cycle of pain, and through a regular course of treatment, these pains can be cured. However, if the pain is caused by bad habits such as sedentary lifestyle, muscle stiffness, cold and dampness, weight-bearing strain and aging degeneration, etc., and these causes are not corrected, then the body is not free from the “soil” of pain, and the pain can be relieved for a period of time or even temporarily cured by treatment, but it may eventually recur. The pain can be relieved for a period of time or even temporarily cured by treatment, but it may eventually return. 5.How to avoid recurrence after the pain is relieved by treatment? As mentioned above, it is very important to correct bad habits and get rid of the pain “soil”. In addition, for recurring chronic pain, we will give some recommendations for reasonable rehabilitation exercises, which patients need to practice. Of course, maintaining regular contact with the pain physician and working together to combat pain is the basis for avoiding recurrence and obtaining long-term results.
