I have developed two blood clots, one in the subclavian vein and one in the inner jugular vein. They are causing my left arm to be discolored, swollen and some pain. PM was implanted a little over a year ago along with a follow up av node Ablation. The PM needs to be moved as it repositioned itself too close to my arm. But at this point that is secondary to treating the blood clot problem. Scary. Anyone else had to deal with blood clots?
