Can you tell me about spinal headache or knows anything about them?

Leakage: It is caused when a spinal needle punctures the dural membrane allowing the leakage of spinal fluid, if the dura is accidently punctured during an attempted epidural the needle is larger and greater chance of a headache.

Iatrogenic goes away: It can happen after any spinal tap, intentional or not, when needle penetrates the layers surrounding the spinal canal. Typically it is positional - worsens with sitting/ standing. Most of the headaches subside on their own, but beacuse it may take up to 10-14 days and in severe cases another injection is offered as a treatment, it is called 'blood patch'.
