Hi All: After looking through several sources, I now have some other names for pseudogout, but no information yet about the disease and breastfeeding. Other names include Chondrocalcinosis and Pyrophosphate Deposition Disease. This is apparantly related to osteoarthritis. I had never heard of this disease before. The literature states it usually hits after age 50, and the mom is only 26. Any information on this and breastfeeding is welcome. Thank you! Margie Forrest, RN, BSN, IBCLC, in WPB, FL
