A lumbar puncture (also called a spinal tap) is a test to check the fluid that surrounds and protects your spinal cord and brain. Your doctor may have done this test to look for an infection. In some cases, a lumbar puncture is done to release pressure from too much fluid or to look for diseases such as multiple sclerosis.
You may feel tired, and your back may be sore where the needle went in (the puncture site). You may have a mild headache for a day or two. This can happen when some of the spinal fluid is removed. Some people also have trouble sleeping for a day or two.
The fluid taken during a lumbar puncture is often sent to a lab for tests. Your doctor or nurse will call you with the test results.
