My hubby occasionally gets what the doc called "silent migraines" - everything but the pain (the lucky b*stard- I always get the whole package- visuals, nausea, light & noise sensitivity and PAIN!). Sounds like this is fairly common, since I know a gal who has them, too.

Fortunately, cannabis takes care of my migraines- haven't had a real one in years. I can still feel them when they try to hit, but they are just a tiny shadow of what I would be suffering without cannabis! I can deal with them.
