... 4bypass surgeries and my last one was this past Nov. I am 47 yrs old. Now on massive amounts of warfrin . My life has been on a roller coaster ride with good luck and then it ends. Now they have no idea of how long this one will last or what they will due when it ends but I constantly have significant pain in my legs between sharp stabbing to cramping in my legs and feet. I also get so tired from walking and I just not sure what to do any more. Hopefully someone else has had this problem also? If you have these problems let me know? How did you take care of it?
