If the condition allows, you can drink more warm water to promote tissue metabolism, which can also relieve the pain. Second, if it is lumbar anesthesia or epidural anesthesia, because the anesthesia is carried out by needle from the back, it has certain trauma, which also leads to soreness and pain, with the extension of time, the trauma can gradually recover, you can do appropriate physiotherapy or hot compresses, which can help to relieve the symptoms.
