You and yours are in my prayers. And yes my husband's stomach was hard before they started tapping it, that was one of the things that told me something was wrong.
Michele, I am so sorry to hear that Lee has taken a turn for the worse. Is Hospice coming to the house? It's good that you have support from family right now. The liver can turn hard and if there is unrelieved ascites, the abdomen can distend so much that it feels hard.
My thoughts and prayers are with you for the strength to get through these hard times.
