The first thing you need to do is to actively identify the cause of the pain in your leg and then treat it accordingly. In most cases, there is no need for closed needle treatment. In most cases, for localized pain points, closed treatment can be carried out, in which case the recovery effect is better. If the pain in the leg is caused by lumbar disc herniation, because after the disc herniation, it will compress the nerve root, and the area within the innervation range of the nerve root, such as the area of the leg, will have radioactive pain, soreness and swelling. In this case, closed needle treatment is definitely not good, because the root cause of leg pain is in the lumbar spine, so you need to actively pay attention to rest, nutritional nerve, dehydration and swelling treatment, closed needle is not able to solve the problem.
