How long does nerve block needle therapy work

The effect of nerve block therapy varies from person to person. Generally speaking, the effect time is very fast, and the effect time is generally about 1 to 3 minutes, which can be maintained for about three months to half a year. Nerve blockers include local anesthetics and long-acting corticosteroids. Local anesthetics, such as lidocaine, are combined with long-acting corticosteroids, such as triamcinolone, betamethasone, and dexamethasone. In general, anesthetic effects last only a few hours, while long-acting corticosteroids can last for months. However, nerve tissue drug therapy should not be carried out frequently, one to three times a year is recommended, otherwise there is a serious risk of local suppurative infection.
