The most common clinical cause of right-sided lumbar distension is lumbar disc herniation, in which a herniated disc compresses a nerve, causing radiating pain or soreness in the muscles of the innervated area. For this kind of disease, we should actively improve the lumbar spine CT or MRI examination to clarify the segment of the lumbar disc herniation and the degree of herniation. 85% of patients can be cured by conservative treatment, that is, medication, with lumbar traction, massage or electrotherapy. The main choice of drug treatment is non-steroidal anti-inflammatory and analgesic drugs with dehydration and swelling or muscle relaxation drugs, commonly used drugs are Cilabao capsules, Nimesulide dispersible tablets, abortifacient tablets, Eperisone tablets or Tizanidine tablets. If the pain point is fixed, the patient with more obvious lumbar distension can also undergo local drug closure treatment, which mainly uses medium and long-acting hormones with local anesthetics.
