The right one is doing fine since the surgery last winter (I was cut from the waist to the ankle), but have the same problem with the left one. Another CAT scan showed a blockage in both the femoral artery on the left side just below where it splits to each leg and at the knee in my left leg. They're going to go in through the stomach in 7-8 weeks to fix the main blockage, hopefully I won't need a second one for the knee, they'll cut me like the right leg. It is what it is, but when all is done, I should be back to normal with good circulation and should be able to roam the mountains again.
