I was on a 2-day prep pkg for a colonospy procedure and went into atrial fibrillation and hospitalized 5 days.I am still having much distress shortness of breath, racing heart and gained 11 pounds of fluid - I have elephant legs and feet, etc. I believe my electrolytes are totally imbalanced. How do I regain my health? I am 73 years old. Thank you. The cardiologist referred me to family care physician and my fcp referred me back to cardiologist. I am frustrated and do not want to continue on 2 kinds of blood pressure, a blood thinner, Lasix, etc.
