An LP is not really fun, but also not a big deal. I had a really rough one and I was fine 24 hours later.
The cyst is real, whether it is related to the migraines or not. Has your doc checked your hormone levels to see if the pituitary is affected?
I would probably do both... diligently look for and eliminate my trigger and get the LP.

I don't know. I'm answering because I suffered from migraines multiple times per week at one point in my life. I was at my wits end, and no one had any answers for me. I discovered by accident that it was aspartame. I'd been a Crystal Light drinker daily, but didn't have it while on vacation for a few days. As soon as I came back, so did the migraines, and I tried eliminating artificial sweeteners. I've had maybe 4 migraines since 1998. I hope you find relief.
