Can a lumbar puncture cause Cauda equina nerve injury?

Most patients after lumbar puncture report headache after lumbar puncture. Generally, this kind of headache is caused by the doctor's retention of some cerebrospinal fluid during the puncture process, resulting in a temporary decrease in cerebrospinal fluid pressure. The characteristic of this headache is that the patient will relieve or even disappear when lying down, but the headache will be aggravated when the patient sits up or stands up. In this case, you can drink more water, often in 1-2 days will gradually disappear, do not panic, but if accompanied by long-term headache that may need to go to the hospital in time to check whether there is a neurological disease.

Another representative sequelae of lumbar puncture is cauda equina nerve injury. It is believed that most people know relatively little about cauda equina nerve. The cauda equina nerve is composed of 10 pairs of nerve roots originating from L2-5, S1-5 and caudal ganglia. It doesn't mean that the cauda equina starts at L2. The cauda equina connects to the spinal cord at the conus medullaris level in L1, so the cauda equina is equally likely to suffer if the upper nerve is damaged and something goes wrong.
