What is pseudogout? What are the differences between gout and pseudogout?

Pseudogout is a kind of arthritis. Patients are likely to suffer from sudden, painful swelling in one or more of their joints. The condition can last for days or weeks.

The most commonly affected joint is the knee; wrists and ankles are less often involved.
In many cases, there are no symptoms. However, during a pseudogout attack, the affected joints are usually:

  • Sudden, intense joint pain
  • Swollen joint that’s warm and tender to touch
  • Red or purple skin around the joint

Calcium pyrophosphate dihydrate crystals within the affected joint
