My mother is only 66, but has diabetes and has regular mini strokes since her first big one a few years ago. Slowly over time, one problem after another bothers her: her ears make her dizzy, her sugar is out of control no matter what she does,her back aches, her legs ache, the heat brings on strokes, etc., which it has kept her in bed a lot. I've been taking her out for walks, but she's become so weak and cannot hold herself up any more with the help of a walker. She collapses to the ground. What can I do?
