I would make your doctor aware of this.
Am I correct in assuming that you had veins taken from your legs for the grafts?
Did they use any of the Arteries in your chest for grafting, such as the Lima or Rima?
If veins were taken from both legs, it is normal for these areas to feel numb for a long time. I had two veins removed from my right leg and the area felt numb for around 12
months. I assume you was put into a rehabilitation program where experts get your
level of fitness raised and assess your progress? You need to exercise to get your
heart healthy again. Did you suffer heart attacks and suffer heart tissue damage?
