The stabbing pain on the right side of the back may be caused by the following reasons: first, it may be caused by acute injury here, such as a sprain or a direct violent blow to the patient during strenuous activity, which may cause an acute sprain of the lumbar muscles or a fracture of the transverse process of the lumbar spine, which may cause a very obvious stabbing pain in this area. Secondly, this condition may be due to old injury, if there is some very serious injury in the past, but not after proper treatment, after its recovery, there will be bruising here, once the patient has a cold or overexertion here, there will be another attack of stabbing pain symptoms. Third, this condition may be caused by lesions in the urinary system, such as acute nephritis, kidney stones, ureteral stones and other diseases, there may be stabbing pain here. Fourth, this condition may also be caused by peripheral nerve lesions, for example, when there is a lumbar disc herniation, it may produce a tingling sensation due to the stimulation of the relevant nerve roots.
