A. Drugs 1, the role of drugs; anti-inflammatory, pain relief, blood, nerve nutrition, nerve repair. 2, the side effects of drugs; is a drug three poison, any drug used well is a drug, used is poison. 3, the toxicity of drugs produced; 4, long-term, small doses of use. 5.Short-term, high-dose use. Tong’s non-invasive intervention has been carried out for more than 20 years, during which we have made several adjustments to the variety of drugs in a timely manner according to the efficacy and clinical response of the patients. At present, we choose drugs with low side effects and good efficacy, except for Salvia, which are all imported from Japan. In response to the principle of side effects of drugs, and according to the mechanism of treatment of lumbar dystrophy, we adopt the method of not short-term, high-dose medication; nor long-term, small-dose medication. We inject small doses of drugs, and let the drugs in the last period be absorbed and excreted before doing the next one, so that the drugs do not accumulate in the body, which reduces the side effects of the drugs and gives full play to the effects of the drugs.

Risks and Complications Tong’s non-invasive interventional treatment is clearly displayed due to the high precision CT scan, guided by the lumbar intervertebral disc, sciatic nerve, blood vessels, soft tissues, intervertebral foramen, small joints of the vertebral body and other tissues, plus more than 20 years of experience in the operation of interventional treatment, making the risk of Tong’s non-invasive interventional treatment reduced to zero.
