Hi Barry sorry no one has replied yet. I am T4 with spread to lymphs and bones and am 55 yrs old. I’m not on Enza yet as I rejected it up front. I just went for injectable HT using Decapeptyl. My blood pressure has got higher over the 2 years I’ve been on it for sure. Any castration level HT triggers heart disease. Tinnitus ?? Yes for sure , but my wife and I feel that Covid vaccinations started that. Many many others have said the same. But yes high blood pressure can cause it. Headaches no , I never have them. Best wishes
