Hello and thanks for writing. I can understand your concern and would try to help you in the best possible way. Some dull type of discomfort is expected post coronary stenting as your body is getting adjusted to a foreign material. Usually this feeling takes few weeks to go as the body adjusts to the stent. However if you feel severe chest pain, sweating, lightheadedness, dizziness you have to rush to your doctor immediately. Fatigue usually developed in this period due to constant bed rest and inactivity which is required after the procedure. You should now start light activity like walking and doing some light work. It would increase your energy levels and take care of the fatigue. I also advice you to take all the medications as prescribed by your doctor and always consult him before altering any medication.
