I have hormonal migraines once a month around the time of my menstrual cycle. Mid way, I get a strange sensation on the left and right sides of my brain, not at the same time though, but sporadically. Today it’s the right side. It feels like someone is pulling my hair slightly. It’s not painful, just weird. Is this signs of a migraine starting up? I’ve been feeling this for 3 days now but I’m still 2 weeks away from my period. I hope it isn’t a migraine.
