Warfarin Sodium and lexapro

After sinus surgery March of 07, I developed a large superficial blood clot in my left thigh. The doctor started my on 1 Lovenox shot and 5 mg of Warfarin a day. After 4 days, I felt a pressure and heaviness in my chest, and was diagnosed with bilateral pulmonary embolisms. Was in the hospital for 3 days and Lovenox was increased to 2 times a day. After being discharged, it took me nearly 2 months to feel normal again, but I still had to remain on 5 mg of Warfaring for 4 more months. Everything was fine until mid August when I missed taking the Warfarin for 6 days. Once I started taking it again, I started feeling terrible......pressure and squeezing feeling in my chest, anxiety attacks, dizziness, feeling hungry, diarrhea and nausea at times. One evening I went to the ER because I thought I was having a heart attack. All the tests showed I was not having a heart attack, and the D-dimer test showed I was not having blood clots. Even had a cardiac CT scan that was completely normal. It is time for me to get off the Warfarin now, but my doctor doesn't want to take me off it until these other symptoms go away. The doctor now has me taking Lexapro (for anxiety) and Prevacid (for acid reflux), and I am going to see a Gastroenterologist to see if I have acid reflux. I don't know if Warfarin is the cause of my problems, but until all this happened, I was a healthy 59 year old female. I just want to feel normal again!
