How painful is a spinal tap?

Varies: This depends on how it is done and by the skill of the person doing it as well as whether there are significant degenerative changes present or a spinal deformity. Obesity can make it more difficult to do and the reason for the spinal tap may affect the result. The size or bore of the needle can be a reason as well.

Not bad: Usually only takes 5-10 minutes to perform. Although it can be a little uncomfortable, it is usually well tolerated.
