Once more I am being told I am too young for something. You would think that at age 50 you are no longer too young for anything. I was too young at age 46 to be diagnosed with PD and now I am too young to need a knee replacement at age 50. However, my tremor has aggrevated my arthritis so much that the neuro thinks I need the replacement in order to be able to continue exercising and thereby resiting the advancement of PD. Sounds like a catch-22 if you ask me. I am doomed if I do and doomed if I don't. I will see the ortho next month and find out what he says (after I argued with the gp to get there). I will let you all know how it comes out. Marling 50/46/who knows when it started
