I haven't been on here for quite awhile. I've been up and down alot. I finally got my doctor to refer me to Oregon Health And Science University in Portland. My appt is for the 30th. If they can't help me, I don't know where I'll turn to next. I do have a question. Does anyone have trouble sometimes focusing their eyes? And do you get headaches alot? Carol Also, the one's who are on heparin, is it helping you?
