I had/have Chronic Heart Failure. Could not take a breath. Scared the S&*t out of me. Have cut back on sodium salt. Because I'm in a wheelchair from a stroke, fluid keeps accumulating. At this point, my legs have so much fluid, walking, even w/ a walker is not working. The condition is self-perpetuating (if that's right). I feel OK, just waiting for the S%^T to hit the fan. NOT fun.
