After minimally invasive surgery for lumbar disc herniation, the symptoms become more serious or new uncomfortable symptoms appear, which may be caused by lumbar spine edema, nerve compression and other factors, and need timely medical treatment, such as surgical treatment, medication and so on. 1. Lumbar spine edema: lumbar spine edema may appear in the short term after minimally invasive surgery, which can be temporarily observed and treated with symptomatic anti-inflammatory therapy, and the symptoms will gradually improve. If the symptoms continue to aggravate or do not ease, it is recommended to consult a doctor in time for another surgical decompression treatment. 2. Nerve compression: After lumbar disc herniation surgery, if there are symptoms such as lower limb numbness and insensibility, it may be due to nerve compression. It is recommended to consult a doctor in time and choose the appropriate treatment plan under the doctor’s full evaluation, such as emergency surgical decompression treatment or oral nerve nutritive drugs such as vitamin B6. When symptoms worsen after lumbar disc herniation surgery, it is recommended to consult a doctor to identify the cause of the problem and choose an appropriate treatment plan.
