Yep - I get this on/off too. Having an episode right now! I don't know what a mini stroke feels like but it's what I imagine it to be. I get pressure in the right side on my head which makes my ear, eye and jaw feel funny. The dizziness can be really bad at times too. I've also in the past looked in the mirror for signs of drooping and convinced myself that one side of my mouth is lower than the other
. I've been through all the scenarios like strokes, brain tumours, etc, but I've kind of accepted now that it's probably a migraine thing and it doesn't really scare me now - it's just annoying and uncomfortable. I also have alot of tension in my right shoulder and neck so it could be that too - it's all connected!
