My husband is ill, he hasn t worked in 24 years due to rheumatoid arthritis. He is 60 years old, overweight and inactive. Yesterday he was extremely tired and slept most of the day. When he got up, he can t hold onto anything, he drops everything he picks up. It is both his left and right hand. There is a small bit of drool, but he is just getting used to upper dentures so I m not sure if that is the reason. Why can t he grip anything?
