Felix, sorry to hear about your silent migraines, they are very scary when you first start having them but it is not unusual for them to start at menopause.
I started having them at the onset of menopause and it took me a long time to find a solution. You can read my story in depth on my compounded hormones thread in the Alternative Therapies section on here but briefly, mine were caused by generic hormone instability and oestrogen spikes which were caused by all types of synthetic progesterone and Utrogestan (which I can never use again). Generally speaking but not always, migraines with aura are caused by oestrogen spikes and the problem I had with Utrogestan was that it caused severe hormone instability and subsequent oestrogen spikes because 100mg was too much in one hit.
During the early part of menopause, I had to keep my oestrogen levels very high to keep the migraines away but now I am very post menopause and on a continuous combined HRT regime, I can get away with a lower dose of oestrogen.
It could be that your reduction in oestrogen has kicked them off and you might find they subside once your hormone levels stabilise. I'm afraid only time will tell.
My silent migraines sometimes start with a blind spots but I always have visual disturbance for 30 minutes (scintillating scotoma) which gradually disappears to the upper sight field but I do not have a headache. They leave me feeling tired and spaced out for 72 hours. Is this similar to your experience? Mine follow a very definite pattern and I had them properly diagnosed by a neurologist and a migraine specialist.
Did you have migraines with the progesterone part of your regime?
I hope that helps.
