I have a history of creaky fingers sore hands and feet, nothing I ever needed to see a doctor for except for one episode of trigger thumb which I got a cortisone shot with 100% relief.  

Recently, both my knees flared up with intense pain.  MRI showed osteo, I was treated with synvisc and I am about 50% better.  I've never had any swelling anywhere, just pain and stiffness.   My ortho says its osteo, but isn't it odd that I have bilateral symptoms all over?  Also I have a sed rate of 30, an elevated crp, although ANA and RF are neg.   Could my knees have been misdiagnosed, or does it sound like I might have two kinds of arthritis.  I am considering seeing a rheumatologist.  My PCP left it up to me if I want to persue it.
