I think 5 minutes a day is reasonable, Bobby. 17 minutes is a lot. Overuse of your muscles could cause weakness and make you prone to falls. If you're being overworked at PT, too that would just make things worse

I would ask the PT to reassess you because of your recent falls/near misses to see if she can detect any new issues JIK something new is going on.

Do you think you are buying more and eating things you shouldn't because of loneliness?
