I now have two canes...a fold up one and a regular one. I use the regular one a lot. Makes me feel my age. The physical therapists are young so I don't know if they have the experience to recognize that I might need to see the doctor. the guy that owns the place hasn't talked to me at all. He has a ph.d. and I don't know what else in p.t. Maybe I should ask the girls if they should ask him. I admit I am not doing any exercises at home. I am too tired.
