Patients should keep their heads elevated for 24 hours following the procedure, explains Resurgens Spine Center. This requires sitting in chairs or raising the head with pillows while in bed. During this period, at least eight large glasses of liquid — excluding alcohol — should be consumed.
Neither aspirin nor ibuprofen should be self-administered to deal with the headache, because they tend to thin the blood, according to Resurgens Spine Center. However, upon patient request, medical personnel are able to offer another analgesic agent, Johns Hopkins Medical advises.

To repair this, blood is drawn from the arm and injected into the site of the leak. This typically halts seepage and eliminates the headache.

The scan itself is not painful, Emory Healthcare explains, but some patients find the injection process uncomfortable.Learn more about Diagnostics & Imaging
