Hi Sammas
Just read your post.
I think it's the prog in your hrt.
When I was on Femseven patches, I had terrible migraines, couldn't carry on everyday like that, so swapped onto Femoston , which still gave me headaches, but not migraines, also I'd get what felt like pressure behind my left ear, radiating up on to the side of my head. Also, if i doubled the dose, because I felt I needed to, I'd get chest pain, then when I dropped back down they would go, so that told me it was the prog. (I'd done that a few times, and it was always the same).
Now however, I've dropped right down to only 1mg femoston, and I haven't had a headache for a good few days. How I get on with that is anyone's guess, but sometimes you just get soo fed up suffering headaches everyday.
Plus, what the ladies have said, maybe your own hormones are coming into play as well.
