Are you taking estrogen as well as progesterone? I have found myself that without the progesterone (topically compounded 40mg a day dosage) 6 days a week, I get feelings of whole body vibrating and electrical shocks. This started at the age of 49. I started on compounded biest at age 51 (1 mg.) 6 days a week. I think that covid (being sick) stressed your body to the max and you might need a tad more estrogen and progesterone until your body regulates itself or that you are not on enough Estrogel/progesterone.
