Leg pain caused by herniated lumbar disc can be treated as follows: First, absolute bed rest. It is necessary to lie flat on a hard bed for at least 2-3 weeks, and external fixation of the lumbar region with a lumbar apron or external fixation of the lumbar region with a brace when leaving the bed to prevent the lumbar disc from protruding and further compressing the nerves and causing pain. Secondly, traction treatment can be carried out. Traction of the lumbar region can be carried out in the Department of Traditional Chinese Medicine and Physiotherapy, which can make the herniated disc retract, thus relieving the compression of the lumbar disc on the nerves and relieving the symptoms of lumbar and leg pain. Finally, oral medication is available. If the herniated disc causes leg pain, you can take oral nerve-nourishing drugs and pain-relieving drugs, such as methylcobalamin tablets, vitamin B1 and vitamin B6 tablets, oral anti-inflammatory and pain-relieving drugs, such as meloxicam and celecoxib, and oral aminoglutethimide tablets for severe pain. If the above conservative treatment is not effective, and after 2 months there is still leg pain or leg pain continues to worsen, then minimally invasive surgical treatment for herniated lumbar disc or incisional surgery can be considered.
