Hello Ladies. I recently added testosterone to my HRT cocktail. I am also hypothyroidic and taking Synthroid. The testosterone is giving me heart palpitations and jitteriness that I was not prepared for. A little research showed that testosterone increases free T4 and reduces TSH, which is why it feels like my Synthroid is suddenly in overdrive. But Estradiol does the opposite! I am stuck in this hormonal conundrum and meanwhile my heart might explode. Has anyone experienced this before and how do I find balance? *Also worth noting that the Testosterone is non-negotiable because my menopausal brain fog was unbearable (I quit my job because I no longer felt qualified). Can anyone help me sort out this mess?
