Yes. I was having balance issues, and I wanted to know why I couldn't balance on one leg no matter how hard I practiced. So I went to a neurologist who gave me a workup, which included blood tests your primary care doctor doesn't do, like IGM, IGG and IGA. Free light chain, and whatever. When he got the results he referred me to a hematologist at a cancer center. I was stunned. But through a connection I ended up at Mayo, and that's where Dr. Fonseca told me this was not my ticket to the other side.
