Neurologist,  's  Response
Might be your doctor is suspecting infection spreading to brain (meningitis/ encephalitis), for which he planned brain fluid test (CSF examination). CSF examination is usually done by lumbar puncture (putting a long needle in between vertebral bones in lower back).
It seems diagnotic test in your patient, to check for infection in brain
There is a small risk of complications of lumbar puncture- infection at local site, spread of infection from puncture site , local hemorrhage, post lumbar puncture headache. But these complications are very uncommon if proper aseptic conditions are maintained and performed by thin needle (21/22 gauze).
