I'm not a doctor, so I don't have all of the answers, but I don't think they do either, so with that said, in my situation CHF was characterized with extreme swelling in my lower body, starting at liver level. If I cut myself anywhere below the liver, I didn't usually bleed, but the area simply weeped with a clear fluid, and took a very long time to heal. I noticed having great difficulty with walking, or standing, and my energy level was extremely low.
