In the clinic, there are many patients with neck, shoulder, low back and leg pain who are unwilling to undergo surgery for various reasons, while general conservative treatments, such as acupuncture, massage, Chinese medicine and other means have all been used, and the pain is still the same, is there really no other way? In fact, small needle knife is a very effective way to treat neck, shoulder, low back and leg pain. We follow a principle of conservative treatment → minimally invasive treatment → surgical treatment for neck, shoulder, waist and leg pain. Generally, we first use traditional conservative treatment, that is, those methods mentioned above; if the effect is not good, at this time, we have to choose minimally invasive treatment, there are small needle, ozone, and radiofrequency ablation, discoscopy, etc.; if the effect is still poor, it means that the lesion is too serious, and it must be open for surgical treatment. In terms of minimally invasive treatment, we choose the knife as the first choice, through a knife blade about 1 mm wide to release the abnormal pain reaction points, these abnormal pain points around the soft tissue is often the accumulation of pain-causing substances, and is in an abnormally high state of pressure, the needle knife can reduce the pressure of the local tissues, so that pain-causing substances can be released, so as to relieve the pain. The entire process can be completed in just 3-5 minutes without the aid of any anesthetic or complex instruments. Our treatment of patients with cervical spondylosis, frozen shoulder, lumbar disc herniation, lumbar spinal stenosis, lumbar spondylolisthesis, etc. found that the treatment of cervical, shoulder, lumbar, and leg pain pain with small needle knife has really unique effects.
