What Are the Benefits and Potential Risks of Throat Closure Injections?

The main function of the blocking injection is to reduce inflammation and relieve pain. It has a good therapeutic effect on bone and joint diseases, acute and chronic soft tissue injuries, or degenerative changes. However, a few patients may experience temporary worsening of pain or infection after receiving the blocking injection. Frequent use of blocking injection may lead to soft tissue damage such as tendons and ligaments, or adverse reactions such as centripetal obesity.

Blocking injection, also known as blocking therapy, can block the transmission of pain in the neural pathway, maintain the normal function of the neural center, improve tissue nutrition, and promote the resolution of local inflammation. The solution in the blocking injection is generally a mixture of drugs such as procaine, lidocaine, and glucocorticoids. Blocking injection is often injected into muscles, fasciae, tendons, joints, and even the vertebral canal of the diseased area. The deeper the needle is inserted, the stronger the pain sensation will be.

One to two days after receiving the blocking injection, some patients may experience symptoms of increased pain, which is related to the increase in local pressure, but it will disappear soon, and the anti-inflammatory and analgesic effects will gradually emerge. Although the needle hole left by blocking therapy is very small, it is still an invasive therapy. A few patients may develop infections if they do not pay attention to keeping the wound clean and hygienic. In addition, if patients receive blocking injection for a long time, the hormone drugs used may lead to centripetal obesity, hirsutism, and other sequelae. Some patients may also experience decreased resistance and osteoporosis.
