Hey. I'm 22. In April of this year I was diagnosed with several blood clots in both lungs. I take high doses of warfarin daily, 25 mgs. In June I started having severe leg pain. A few days later it was in my back. Now I have severe pain everyday of my life. Have to take pain pills so I can move. I visit the Dr every week. And frequent er visits. I'm tired of taking pills. They say my clots came from smoking and birth control pills. My INR levels have not been therapeutic ever. Please help me.
