Hi, I have been getting really bad headaches either in the run up or during my period for a while. This cycle my period started on Sunday , and for the last 3 nights I've had a thumping headache like I've been hit by a baseball bat. It's only on one side, at the back of my head. My scalp on that side is tender too. It's been so bad I've taken paracetamol and nurofen together (I don't usually take painkillers) and they don't get rid of it. I haven't had nausea/ aura or any other symptoms. Will go to GP but wondering if this is likely to be a migraine? Does anyone get similar headaches around their period and any suggestions of how you have prevented / treated them? Thanks!
