I was on syntest for eight months and during the eighth month I started experiencing chest pain and shortness of breath. I was told to immediately discontinue the syntest, which I did. The menopausal symptoms immediately returned. Over the course of 1 1/2 years I've consulted with three different doctors, tried bio-identical hormones and many different delivery systems, but always experience chest pain with whatever I try. Is there any kind of estrogen out there for me?
