Pain in the left lower limb after an epidural injection

The cause of pain may be repeated puncture. When the puncture needle touches the nerve root for the fourth time, the patient suddenly feels the pain of the left lower limb. The most important thing is prevention. Pay attention to puncture techniques and improve puncture techniques. When there is any abnormal sensation, pull out the needle immediately, do not insert the tube, and resdule the operation or change the anesthesia.
