What should you know about pseudogout in fingers?

Pseudogout is also called calcium pyrophosphate deposition disease. Crystals inside a joint can trigger inflammation, making a finger joint warm, puffy, tender, and difficult to bend. A flare may affect one joint or several and can interfere with typing, dressing, or holding objects. Finger swelling can also come from injury, gout, osteoarthritis, rheumatoid arthritis, or infection.

Assessment may include an examination of the hand, review of the onset and pattern, and imaging or joint-fluid testing when practical. The appearance of a swollen finger cannot establish the cause on its own.

Reduce forceful gripping and repetitive tasks while the joint is sore. Elevate the hand, keep rings off a swollen finger, and apply a wrapped cold pack briefly. Keep nearby joints moving gently if movement is comfortable, but do not force a painful bend. Use anti-inflammatory medication only after a clinician or pharmacist checks it against your health conditions and current medicines.

Record which finger and joint are affected, whether the skin is hot or red, and how quickly the swelling appeared. This information can make the appointment more useful.

Arrange prompt assessment for a first episode of a hot, swollen finger or swelling that limits hand function. Seek urgent care if fever, chills, rapidly spreading redness, a wound, severe escalating pain, numbness, or a pale or blue finger occurs. After an injury, urgent review is needed if the finger is crooked or cannot be moved.

Ask which joint is involved, whether fluid testing or imaging would clarify the cause, which treatment is safe for you, whether an injection is appropriate, and how to protect hand function during recovery.
