Diuretics are not going to solve your kidney problem and they could make your situation worse rather than better. I would urge you to seek professional advice before taking them.
It sounds like your lymphatic circulation is poor in your legs just like the circulation in your kidneys is very poor. The legs and kidneys are next to each other in the iris and one affects the other. That is why I said I regret ever injecting my legs because it affects the nervous system balance which is affecting the healing of my kidneys by serrapeptase and nattokinase. Poor circulation in one can also mean poor in the other.
