Crystals, Pseudogout

CPPD is a type of arthritis that, as the old name of pseudogout suggests, can cause symptoms similar to gout yet a different type of crystal deposit triggers the reaction. CPPD can cause bouts of severe pain and swelling in one or more joints which can limit activity for days or weeks. It also can cause a more lasting arthritis that mimics Osteoarthritis or Rheumatoid Arthritis. The condition most often involves the knees but can affect wrists, shoulders, ankles, elbows, hands or other joints.
