I am a 38 year old male. I started taking Levothyroxine about a year ago, and then testosterone injections a few months later. I have a significant family history of heart disease. I had a heart attack in August, and a stint put in the anterior artery. Since then I am on the typical cardiac concoction of Lipitor, aspirin, Metropolol, Losartan, Clopidogril, and Omega-3. I never felt any improvement in how I felt after taking the Levothyroxine or the testosterone, and have felt progressively worse over the last couple of months. Lately I have been experiencing brain fog and a pressure feeling in my head and base of my skull, with some feelings in my throat as well. I am also under a lot of stress at work (I am an attorney and am currently leaving my firm to start my own). I am not happy with my PCP because they will change the thyroid and testosterone medicine amounts and then wait six months to retest my blood. What could the brain fog and head pressure be? Thank you for your time.
