Final answer:
Reactive arthritis, also known as Reiter Syndrome, manifests with the triad of symptoms: conjunctivitis (can't see), urethritis (can't pee), and arthritis affecting joints like knees and ankles (can't climb a tree). It is an autoimmune response leading to inflammation in various parts of the body also seen in conditions such as RA, which similarly involves painful, swollen, and stiff joints.
Step-by-step explanation:
Reactive arthritis (Reiter Syndrome) is characterized by a triad of symptoms often simplified by the mnemonic: can't see, can't pee, can't climb a tree. The phrase captures the syndrome's main symptoms: conjunctivitis or uveitis (can't see), urethritis (can't pee), and arthritis that can affect the ankles and knees (problematic when climbing a tree).
Inflammatory conditions like reactive arthritis or rheumatoid arthritis (RA) involve the body's immune system attacking its own tissues. RA is known to primarily affect the synovial joints, leading to symptoms such as swollen, stiff, and painful joints. These autoimmune conditions show the complexity of immune system responses, which can lead to various symptoms including fatigue, fever, joint pain and swelling, and in the case of RA, long-term damage to the joints.
