Nerve block therapy is usually applied to tendinitis, bursitis, synovitis, lumbar disc herniation, ligament tear and other diseases, which can significantly reduce the patient’s pain and reduce local inflammation. It involves localized injections of lidocaine combined with vitamins, steroids and other medications into the painful areas of the body to block and diminish local nerve sensation, thereby reducing pain, numbness and other uncomfortable symptoms. In addition to injecting directly into the painful area, the doctor will also choose a more appropriate injection point in the innervated area according to the pain point in order to achieve a small amount of injected drugs, can relieve a large area of pain. It is effective and has low side effects. However, if severe and prolonged numbness in the toes has already occurred before the nerve block operation is performed, it may not be fully recovered after the operation. Seek prompt medical attention in these cases so that the doctor can determine the cause and dispose of the problem accordingly.
