Doctors had diagnosed me wth Raynaud's for a long time. When I was scheduled for surgery on my shoulder the pre-surgery bloodwork showed a very low platelet count. My surgery was cancelled, and I was referred to a hematologist. I had a bone marrow biopsy and was told I had ITP, MGUS and Cold Agglutinin Disease or CAD. When I'm cold CAD causes antibodies to attack red blood cells and was the reason for my blue fingers when cold. I was told it is very rare and there is no cure.
