Hi! Before diagnosis I had constant migraines every day. It was awful. My cancer was estrogen positive, so I believe it was the estrogen causing my migraines. After surgery headaches gone. However now on on Tamoxifen, I have slight headaches if I haven’t drank enough water throughout the day. I hope your headaches get better! Hugs!

@A MyBCTeam Member I have learned it is the unstable estrogen levels that cause migraines. I stopped, started AIs so often the estrogen was up/down. Ex, many women during periods have migrains as estrogen levels fluctuate. At least off AIs,the estrogen could stabilize. Today a stomach sick headache and this is with monthly preventive injections. This too will pass.
Thx, Faith.

Do you have recurring migraines and she informed you estrogen changes would make them worse?

My oncologist informed me of all side-effects. She's the greatest
