I was injected with steroids which have been identified as coming from a contaminated batch. where is a lumbar puncture done - what part of body?

On lower spine: These are commonly performed in the lower back but the infection can spread throughout the central nervous system.

Symptoms?: At this point, there have been less than 120 cases in 10 of the 23 states where the more than 17000 vials were sent. Lumbar punctures should be done if a recipient has compatible symptoms.

Lower back: A lumbar puncture is performed in the "lumbar" area of the spine -- it is in the lower back.
