Ski,
Thanks for your quick reply. I think you’re right about blaming all of our ills on Graves’. In addition to the Graves’, I also have Mitral Valve Prolapse (diagnosed at the same time as my Graves’ disease). Anyway, I searched on-line and found that exercising in cold weather with that condition can cause the symptoms I had. I’m due for visits soon with my endocrinologist, and my primary care physician, so I will discuss that with both of them.
Thanks again for your help!
