Has anyone else had relief from Marijuana?

Sometimes I’ve been uncertain whether it was the weed or not. Today I had I migraine come on and yes I had already taken naproxen. Probably about 20 minutes previously with no relief yet. I figured instead of continuing my normal relief routine, I would test my Marijuana theory. I sat down and took a very small dab, careful not to make myself cough. I literally feel just about fine now.. now this doesn’t always work, and I don’t know why it even did or does. Also, I primarily smoke flower, not concentrates. Just what I happened to have. Would love to hear people’s thoughts and experiences as well as insight.
