i started on warfarin 10 weeks ago for a single medium P.E. on my left lung (this could be because i have had difficulty in moving around for the past three years following spinal surgery). However, at first i felt fine on warfarin, but in the past four weeks i have noticed changes. Sometimes i get fluttering in my chest but only last for about 2-3 seconds then goes away, Doctors told me this is how my body reacts to the clot. I also have some aches in my limbs and back (put this down to the new job). Furthermore, i have noticed hair loss and damaged, fragile hair. When this P.E. occurred i was walking with a stick due to the spinal surgery. But once i started taking warfarin my back has recovered so much so that i have returned to work after 3 long years. The job i perform now is doing removals and H.G.V. driving. I am only 34 years of age and i am taking 9 mg of warfarin a day (with a INR of 2.6) and 30mg of Lansoprazole a day for my stomach (you can feel a bit bloated sometimes).
