I Have AF And Heart Problems Foseveral Years. The Problem

I have AF and heart problems foseveral years.
The problem I want to solve is water blisters on my legs from just below the knee to my feet.
These blisters break and the water runs down my legs.
I have been taking 40mg of forosamide but increased to 80mg., it has helped take the pressure off but they are still leaking but less than the beginning.
Should I also reduce my liquid intake, and how much?
Im a 73 old male with heart problems for about ten years, AF, Pacemaker, bypass, congestive heart failure.
One more point, the blisters break and for some very thick scabs.
What would be the best way to soften them and releive the pain.
Thank You
