Irene - thanks so much for sending more information. I will pass this on to my friend Bonnie, who will be joining us at some point. (I have to show her how to navigate the system.) I am so sorry for all that you have gone through with this; I do know that Bonnie will find some comfort in knowing she is not the only one with these sorts of symptoms. Are the doctors you mentioned ones you have worked with? If anyone else has anything else to offer on my questions, I would greatly appreciate hearing from you. Thanks so much, Pam
