Or- I don't recognize them. I do have great difficulty walking, standing and if I do house or garden work I need to take breaks every fifteen minutes to relieve my lower back pain. I have Uveitis and have had it for at least two years. When I last saw my eye doctor he basically just dismissed it. But now I know it is tied to this illness. I am old but very strong. I take care of myself, drive my car, shop for groceries and play a poor game of golf. I am 92. Because I do not complain a lot I suppose people think I am OK but I know I am extremely limited in what I can now do. I am doing floor exercises given to me by PT but quite the treatment at their establishment because I felt I could just as well do the exercises here at home, and I do. My eyes do bother me and I am going to make another appointment with my eye doctor and tell him what I think is causing this condition. I will see where that leads. I do not think I have as advanced a condition as many of you write about but I do know that I walk totally bent over from the hips up and cannot hold my head up when in that position. Sitting - I am fine. Thank you for letting me talk.
