Lumbar Puncture Risks: What You Should Know Before the Procedure
Published: Oct 09, 2023
While lumbar punctures are generally safe, like any medical procedure, they come with some risks. This article will explore potential complications and who might be at higher risk.
Common Side Effects
The most common side effect of a lumbar puncture is a headache, which occurs in about 10-30% of patients. This is usually due to a small leak of spinal fluid and typically resolves on its own within a few days. Some patients may also experience temporary back pain or discomfort at the needle insertion site.
Rare but Serious Complications
More serious complications are rare but can include bleeding, infection, or nerve damage. In extremely rare cases, a condition called cerebral herniation can occur if there's increased pressure in the brain. This is why doctors often perform a CT scan before a lumbar puncture if they suspect high intracranial pressure.
Who's at Higher Risk?
Certain factors can increase the risk of complications. These include bleeding disorders, anticoagulant medications, and obesity. People with spinal deformities or those who've had previous spinal surgery may also face increased risks. It's crucial to inform your doctor about your medical history and any medications you're taking.
Frequently Asked Questions

Balancing Risks and Benefits
