Differential Diagnosis for Debilitating Joint Pain

Single Most Likely Diagnosis

  • Osteoarthritis (OA): Given the patient's age and the location of the pain (hands), OA is a common condition that could explain the symptoms. The morning stiffness and response to celebrex also support this diagnosis.

Other Likely Diagnoses

  • Seronegative Rheumatoid Arthritis (RA): Although the autoimmune panel is negative, seronegative RA is a possibility, especially given the debilitating joint pain and morning stiffness. The response to celebrex could also suggest an inflammatory component.
  • Psoriatic Arthritis: This condition can present with joint pain and stiffness, and the absence of a positive autoimmune panel does not rule it out. A thorough skin examination for psoriasis is necessary.
  • Reactive Arthritis: This form of arthritis can occur after certain infections and may not always have a clear precipitant. The patient's symptoms and lack of positive autoimmune tests could fit this diagnosis.

Do Not Miss Diagnoses

  • Lyme Arthritis: Caused by Borrelia burgdorferi, Lyme disease can lead to arthritis, particularly in the hands. Given the potential severity of untreated Lyme disease, it's crucial to consider this diagnosis, especially if the patient has been exposed to ticks.
  • Gout: Although more common in men, gout can occur in women, especially post-menopause. The sudden onset of debilitating pain could be indicative of a gout flare, and the lack of response to celebrex might prompt further investigation.
  • Hemochromatosis: This genetic disorder leads to iron overload and can cause joint pain, among other symptoms. It's essential to consider this diagnosis due to its potential for severe complications if left untreated.

Rare Diagnoses

  • Relapsing Polychondritis: A rare autoimmune disorder that can cause joint pain and inflammation, among other symptoms. The absence of a positive autoimmune panel does not rule out this condition.
  • Sjögren's Syndrome: Although typically associated with positive autoimmune tests, Sjögren's can occasionally present with negative serologies. The condition can cause joint pain and other systemic symptoms.
  • Sarcoid Arthritis: Sarcoidosis can manifest with joint pain and stiffness, and while it's less common, it should be considered in the differential diagnosis due to its potential for serious complications.
