Differential Diagnosis for General Joint Pain and Bloodshot Eyes

  • Single Most Likely Diagnosis
    • Rheumatoid Arthritis (RA): This condition often presents with symmetric joint pain and inflammation, and while not directly causing bloodshot eyes, the associated inflammation can lead to secondary conditions like scleritis or episcleritis, which could cause the eye symptoms.
  • Other Likely Diagnoses
    • Reactive Arthritis: Previously known as Reiter's syndrome, this form of arthritis occurs as a reaction to an infection elsewhere in the body, often presenting with joint pain, eye inflammation (which could cause bloodshot eyes), and sometimes urethritis.
    • Psoriatic Arthritis: A condition that combines the swollen, scaly skin of psoriasis with joint pain and arthritis, and can also include eye symptoms like conjunctivitis or uveitis, leading to bloodshot eyes.
    • Lupus: Systemic lupus erythematosus (SLE) is an autoimmune disease that can affect various parts of the body, including the joints and eyes, causing pain and inflammation in these areas.
  • Do Not Miss Diagnoses
    • Giant Cell Arteritis: Although less common, this condition can cause severe eye symptoms, including sudden vision loss if not promptly treated, and can also present with joint pain.
    • Sarcoidosis: An autoimmune disease that can affect multiple parts of the body, including the eyes (causing uveitis) and joints, and if missed, can lead to serious complications.
    • Lyme Disease: In its later stages, Lyme disease can cause arthritis and, in some cases, eye inflammation, making it a critical diagnosis not to miss due to its potential for serious complications if left untreated.
  • Rare Diagnoses
    • Relapsing Polychondritis: A rare autoimmune disorder that can cause inflammation in various cartilaginous structures, including the eyes and joints, leading to symptoms like bloodshot eyes and joint pain.
    • Behçet's Disease: A form of vasculitis that can cause a wide range of symptoms, including joint pain, bloodshot eyes (due to uveitis), and oral or genital ulcers, making it a rare but important consideration in the differential diagnosis.
