Hello Vickiers, welcome to HealingWell. So that your husband has this terrible disease. Muscle cramps are a common complaint of liver patients especially when they are on diuretics. It's a fine balancing act that the doctors do with their meds to try and keep them as comfortable as possible.
He needs to have his feces tested for blood or a colonoscopy. Black stools can be a sign of bleeding as June stated below.
As you see, we have a bunch of wonderful people here on this forum.
We are here to help each other get through a very difficult time. So post when ever you like.
When the going gets tough....the tough get going! Don't always know where I going but I get there anyways.
