Lumbar punctures: After a lumbar puncture it is not uncommon to have a headache. If the headache responds to common meds like tylenol (acetaminophen) or Ibuprofen i would not worry. Also if it lasts several days this may be due to a small leak around the puncture and can be remedied by the doctor who did the lumbar puncture. Talk to your doctor. ...Read more

Can 2 MRI tests/lumbar puncture last year cause hair loss now? Tests neg, health ok now. Can radiation from the tests be reason for delayed hair loss?

No: Haven't heard of MRI scans or of lumbar punctures causing hair loss. However, normal healthy people usually don't get MRI scans nor lumbar punctures. That means there must be some other medical problem(s) going on. Perhaps the hair loss is related to other medical issues. ...Read more

Can they take out cfs from a VP shunts valve and measure the pressure to see how high it is instead of needing a lumbar puncture?

Can they take out cfs from a VP shunts valve and measure the pressure to see how high it is instead of needing a lumbar puncture?

Tap: The safest and best route of having CSF removed in anyone, with/without shunt, is via lumbar puncture/spinal tap. An alternative route is a cervical tap, which is higher risk and more painful in general. In the right hands, an LP is minimally painful. I sometimes recommend a relaxing medication prior to having one & request the performing provider use sufficient numbing medication. ...Read more

I need a 2nd Lumbar Puncture due the possibility of IH. Because in the 1st they didn't take the pressure. Is this procedure safe, too often?

Spinal tap questions: This procedure is generally considered safe in an experienced doctor's hands. I would ask how many procedures they have done before. There is also the option sometimes of having interventional radiology do the procedure which might make it easier. There are always small risks with a procedure like that-since it is a very long needle entering a deep space (bleeding, risk of infection, nerve damage) ...Read more
