I Was Recently Diagnosed With CPPD And Have Answers As

I was recently diagnosed with CPPD and have answers as to what has been hurting my joints and problems I have had. It is hard to believe I am 74 and no one ever mentioned this.,...just stating I had a type of arthritis and couldn't figure it out. Even went to say it was a mystery, as from X -rays they saw fused joints in the tops of my feet, hands, etc. Broke my wrist and the radiologist called my son and said he wanted to talk about my condition and how was I being treated. He said my hands and feet were a mess. Why is this so hard to diagnosis?
