I work in the post office and do a lot of heavy lifting, pulling,and pushing of heavy rolling equipment. I am having a cardiac catheterization. I have PAD with blockage in the abdominal aorta and complete occlusion of the superficial femoral artery. The doctor is also going to check my heart arteries with dye. I have plenty of sick leave to use. My question is how many days off work should I request so I don t cause any problems healing.
