The physician injects a numbing medicine to ease the pain, then a needle is inserted into the back to take a small sample of the fluid that surrounds the brain and spine. Imaging tests such as CT scans or MRI scans of the brain may be done to look for swelling and inflammation. Other CT scans and X-rays may be done to look for a source of the infection.

If you have had close contact with someone who has meningitis, ask your physician whether you should take antibiotics to prevent infection.
