I have factor V leiden and suffered a mild stroke 3 years ago at 41. I took warfarin for 1 year. I felt terrible the whole time, I developed asthma for the first time while on it, i was weak,tired ,had numbness and tingling in my lower legs and feet,and felt foggy. The bad thing is that I've been off of it for three years now and definately feel better but still not like I was before. I'm convinced that the warfarin is the culprit and that I may never fully recover.
