Differential Diagnosis for Pain in the Back of the Hand
Single Most Likely Diagnosis
- De Quervain's Tenosynovitis: This condition, which affects the tendons on the thumb side of the wrist, can cause pain in the back of the hand where the tendons are located. It is a common condition that can be caused by repetitive motion or direct injury to the area.
Other Likely Diagnoses
- Tendinitis: Inflammation of the tendons in the hand can cause pain, especially with movement. This is a common issue in individuals who perform repetitive activities with their hands.
- Ganglion Cyst: A lump or mass that forms on the back of the hand, often associated with a tendon or joint, can cause pain and discomfort in the area where the tendons are located.
- Extensor Tendinitis: Specifically, inflammation of the extensor tendons that run along the back of the hand can cause pain in this area, especially when extending the wrist or fingers.
Do Not Miss Diagnoses
- Infectious Tenosynovitis: Although less common, an infection within the tendon sheath can cause severe pain, swelling, and potentially lead to serious complications if not promptly treated.
- Gout or Pseudogout: These conditions can cause sudden, severe pain and swelling in the joints of the hand, including the area where the tendons are located, and require specific treatment to manage symptoms and prevent long-term damage.
Rare Diagnoses
- Tendon Rupture: A complete or partial tear of a tendon in the hand can cause sudden pain and loss of function, although this is less common compared to other diagnoses.
- Sarcoidosis: A rare condition that can cause inflammation in various parts of the body, including the tendons of the hand, leading to pain and swelling.
- Amyloidosis: A condition characterized by the deposition of abnormal proteins (amyloid) in various tissues, which can rarely affect the tendons and cause pain and dysfunction.
