How long will the nerve block needle return to normal

The nerve block usually returns to normal within an hour. The drugs used for nerve block are a mixture of local anesthetics and long-acting anti-inflammatory hormones, which can have a long-lasting effect after the local anesthetics have lost their effect and maintain the blocking effect. For patients who fail conservative treatment and do not want to take surgical treatment, nerve block can be tried and the principle of step treatment can be followed. However, not all patients can be effective, for immediate, early lumbar disc herniation may be effective.
