Hello, lumbar intervertebral disc 4-5 has been protruding for more than a year, and the local compression may not be serious, so your leg pain is not obvious. If you don't pay attention every day, it is easy to relapse and difficult to eradicate. Only when the protruding part is calcified or the protruding part is large by CT or MRI, it is necessary to choose surgical removal treatment. It is suggested to adopt conservative treatment, such as oral anti-inflammatory painkillers such as fenbid or diclofenac, neurotrophic drugs such as vitamin B 1, and drugs to improve local blood circulation such as Dibazole. At the same time, it is necessary to selectively cooperate with traction therapy, physical therapy, drug fumigation, external application of traditional Chinese medicine or bonesetting massage for reduction. According to the therapeutic effect and necessity, epidural nerve block or collagenase lysis can be selected.
