Sorry to be crashing the post here.
But, I thought I'd add something here. Did you know Olympic Athlete Gail Danvers was diagnosed with Graves three years after being dogged by all kinds of horrible symptoms? She was still trying to run, even without energy and ended up tearing her ACL. Yikes! And, later she learned how the muscles contract, but don't stay limber when you have Graves.
Food for thought on maybe being careful.
