@craigz20 Hello, Craig, and welcome to MayoClinicConnect. We’re not medical professionals or experts, but we all have experiences that we share to help each other. If you’ve not yet had them, you can expect an echocardiogram to look at the function of your heart and several other cardiac tests so the doctors can follow your heart’s health as you get treatment. You will also want to start a notebook with your health history, as best you know it, because everyone will ask. Include family history, especially if someone had/has heart disease; ALL medicines you take, including over-the-counter and Chinese meds. Some of these may interact with the meds you will get for treatment. Speaking of treatment, prednisone or intravenous steroids are the best way to jump-start treatment. Last year I was diagnosed with lesions on my brain and the intravenous steroids brought my brain back. There was nothing else. I have a rare autoimmune disease and the doctors are still researching treatment. The steroids kept me alive! Are you seeing doctors at a major medical center? You might feel more confident with a second opinion on treatment. One of the other mentors may know what Mayo Clinic says about sarcoidosis. I’ll let our expert, @johnbishop , see what he can find. Best of luck and keep in touch, please!
