Pseudogout is a type of inflammatory arthritis caused by deposits of crystals in and around the joints. Although the crystals causing the inflammation are different from those that cause true gout, symptoms are very similar.
Location
Pseudogout most commonly affects the ankles, knees, hips, wrists and shoulders, but it usually only affects one joint at a time.
Characteristics
Pseudogout inflammation is characterized by joint pain, swelling, warmth and stiffness. These symptoms can be severe.
Time Frame
An episode usually comes on suddenly and lasts for several days to several weeks. Episodes can resolve spontaneously. Pseudogout episodes sometimes occur repeatedly and may affect a different joint each time.
Risk Factors
Pseudogout is most common in older adults, particularly those who are dehydrated. Joint trauma can increase one's risk of developing the crystals that cause pseudogout. Genetic conditions are another risk factor.
Treatment
Treatment may include non-steroidal anti-inflammatory drugs and other medications, injections of corticosteroids into the affected joints or removal of fluid containing the crystals.
