In Oct 2011 my mom starting having an all over body itch . this lasted for several days and then one day she noticed pain in the wrist . Within 24-48 hrs the joint pain was in both wrists, shoulders, and knees. So severe that she could hardly walk. SHe had an off the chart C reactive protein , slightly elevated liver enzymes (which were normal with repeat testing). They thought she had mono at that time. After a month of prednisone (starting at 40mg for two weeks, then decreasing by 10mg every week) her symptoms resolved. THe whole cycle is starting again with the body itch starting 5 days ago and yesterday she developed pain in the knee. by today she has increasing pain in both knees, one shoulder and wrist. She denies abdominal pain, no fever, no new medications, no jaundice. What is going on?
