Can lumbar puncture needle leave sequela?

No, now the biopsy is very advanced, the so-called sequela is actually the blood disease after the examination of bone marrow by the biopsy. I'm not sure about the conditioning, but I think this puncture is a very, very small interventional procedure and it's safe to say that as a diagnostic lumbar puncture to take cerebrospinal fluid, according to the medical routine, there will be no sequelae. The main postoperative complications of lumbar puncture are low cranial pressure headache, which is manifested as obvious headache after sitting up, while headache is relieved or disappeared after supine lying. This is mainly because some patients still have partial cerebrospinal fluid leakage from the puncture needle, resulting in reduced intracranial pressure, nerve pulling, and headache. Therefore, patients are generally asked to stay in bed for 4 to 6 hours after lumbar puncture. Drinking more water is also encouraged to prevent the occurrence of hypotensive headache, and even when hypotensive headache occurs, it usually lasts for 4 to 6 days and usually will heal itself.
