[|AI|]  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 diagnostic test in your patient, to check for infection in Braintree 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).
