Thanks to all of you for the excellent and very helpful responses. There is still so much for me to learn. Let me respond to some of your points. I have no issues with hypertension, and no history of heart issues. My cholesterol is only slightly elevated without the statins, so that's a potential area for some dietary changes. I have seen a pulmonologist, who found my lungs clear and health. Thanks for the note on cancer issues. I have a nephew who is a local derm doc and he is happy to check me out whenever I want. I'll be seeing him soon. Some of my other complicating factors are diabetes (well-controlled) depression, Tourette's. The ocular part of my MG is complicated, with double-vision to the extent that I'm probably going to need strabismus surgery in the not-too-distant future. From what y'all are saying, it sounds as though I need to get in to see a cardiologist.

Any more info you can give me is a blessing. I appreciate you all.

Bill
