There are many cases of lumbar disc herniation that must be operated on. Generally speaking, the symptoms are very severe: 1. painful walking and not being able to walk 500 meters. 2. Numbness in the urinary and fecal areas, weakness and incontinence. 3, lower limb pain, numbness is very serious. 4, the back of the foot, toes can not be lifted. The appearance of any of the above symptoms, it lights up the red light, pulling the red line tight, it is dangerous. Find a regular doctor immediately!!! Other cases, such as general leg pain, back pain, numbness is not necessarily an emergency treatment, pain is uncomfortable feeling, but will not die. The herniated disc can also rarely and rarely appear paralyzed. In short, when the symptoms seriously affect work and life, surgery is necessary. Many patients are afraid of surgery and are fooled by various treatment methods, which end up with poor results. My experience concludes that no one can really hide from a patient with a herniated disc in the lumbar spine when the doctor has gone through a strict gatekeeper and determined that surgery should be performed. After a number of hours, surgery is eventually required. Not only do you have to endure half a day for nothing, but the difficulties increase when you actually operate (for example, the appearance of calcification), adding a lot of trouble for the doctor or a new and worse condition. I wonder if we can make a jingle to remember these red lines? The conditions that necessitate surgery are: very painful, numb and immobile, and unable to walk with dysbiosis. If it is determined that surgery is needed, what kind of surgery should be done? This is a matter of discussion with the doctor. It is not up to the doctor alone to decide whether or not minimally invasive surgery can be done. My attitude is to lay out the pros and cons of each surgery so that the patient knows very much and then let the patient make a choice.
