I have had raynauds since 25. I am 80. Have developed several other autoimmune diseases. There was no medicine in my day. I just kept warm and defrosted hands and feet when coming in from the cold. I am now on blood thinners for a PE and DVT and am much warmer. I also live in Florida. My grandson has inherited raynauds. He moved from Jersey to SC. Sorry I’m not much help. But I made it to 80. 😊
