Combination Treatment of Fulvestrant and Verzenio

I'm starting a new discussion of these drugs since the old ones are sometimes different combos. Since my 4.5 month trial of Letrozole ended up giving me super high blood pressure, I've been taken off of it and asked to try Fulvestrant injection with Verzenio pill. They want to shrink my tumor so that they could use radiation (Proton?) to kill the rest. The tumor is within the chest wall, and very inaccessible. Has anyone tried this combination? How did it go and how were the side effects. Thanks very much.
