Thank you all for your responses. This subject is so bewildering to me.

Vicc,
I would very much like to have your info. I did briefly talk to the rheumy on the phone and she did say ischemia is a possibility with me. I have an appointment in October and would like to learn what I can by then.
Sorry to hear that your energy is so low. But I think I can kind of relate. I don't even get on the computer every day. So, whenever you are up to it my email is lindaandsteve2@earthlink.net.
Thanks again,
Linmarie
