Patient: back pain when waking up in the morning, occasional numbness and sometimes pain in the nerves of the left leg. Mainly leg pain. Laboratory test: L3-L4 level lumbar disc herniation. I have done traction, massage, and plasters, all to no avail, and have eaten a lot of Chinese medicine and conservative treatment to no avail. I would like to know if I need to have surgery. It is said that there is instability and slippage of the lumbar spine, do I need to have fixed surgery? The information you provided is incomplete, so I cannot give specific advice. Please add the following information: 1) Lumbar spine front and side, hyperextension and hyperflexion films, and CT films (picture data). 2) The names and usage of specific Chinese herbal medicine, Chinese medicine and western medicine. 3) If there is indeed instability and slippage of the lumbar spine, theoretically it is necessary to do internal spinal fixation surgery, especially for 2 degrees or more The first degree of slippage can be specifically analyzed according to the specific clinical symptoms.
