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 :-)
