1 year ago, I had a massive blood clot on my heart and lungs, which I had open heart surgery, I also had blood clots in my L leg.  My question is I'm on Coumadin and other medications, my joints hurt so much if I sit down or lay down and get up.  My R leg also gets pain in the front of the calf area, it's hurts so bad.  My legs are always feeling tight also.  I do have severe damage to both valve pumps in my legs.  I'm only 53 and I feel like I'm 80 years old.  I have tingling in my hands, burning feeling in some of my fingers.  What could this be, or is it all related to my blood clots?  Thank You :-)
