Hi ElizMcD,
Migraine disease and cluster headache are considered primary headache disorders. This means they are not caused by anything else. They can however, occur at the same time.
A CSF leak is it's own disorder as well, not caused by migraine disease or cluster headache. We have information on CSF leaks in this article I hope you find helpful; https://migraine.com/living-migraine/spinal-fluid-leak/
Wishing you a low pain day,
Nancy
