A 56-year old man presented to the ED after 4 days of hemoptysis and intermittent left chest pain that worsened when he was supine. Ibuprofen(Drug information on ibuprofen) provided some relief. He also felt tired and complained of exertional dyspnea. Joint pain, primarily affecting the knees, shoulders, and elbows also had bothered him for the past few months. His temperature was normal; he had no chills and had not lost any weight. He said he had been treated for “pneumonia” twice during the past month. Past medical and surgical histories were unremarkable. He was a social drinker and did not smoke cigarettes.

The patient was pale and had small telangiectasias on his face. He had mild tenderness over the knees and shoulders. Active and passive range of motion measures were normal.
