Warfarin Sodium and great memory

Thank God I'm not the only one! I was actually relieved when I found this site. I was an active 60 yr. old female until hit with blood clots in lt. leg that went to lungs. I've been on Warifin for almost four months these are my side effects: extreme fatigue, back and leg pain, over-all weakness,decrease in flexability of limbs, dizziness, vision changes even from day to day, memory loss( I've always been known for my great memory). I did mention these to my hemotologist last month and he sent me to ER. Cat scans of head, chest and abdomen all were normal. Every doctor I have seen says Warifin is not to blame but all this has developed since I began taking it.
