What is pseudo gout?

According to Mayo Clinic, pseudogout is considered a type of arthritis identified by sudden swelling and pain in one or more joints. It is called pseudogout due to its similarity to gout.

Pseudogout is caused by crystals, compromised of calcium pyrophosphate dihydrate, forming in the joints and leading to inflammation. Pseudogout lasts for a few days or a few weeks. The knee is typically the most afflicted joint, while wrists and ankles are less often affected by pseudogout. Old age is a factor in the formation of these crystals, with crystals appearing in almost half of individuals over 85. However, Mayo Clinic states that most individuals with crystal formations never show symptoms of pseudogout.
