I was wondering what diagnosis would be suggestive of the following symptoms: Difficulty swallowing and a sore throat. More difficulty swallowing cold liquids than hot ones. Complaints of a burning chest pain while swallowing. Cough productive of clear sputum, and cultures show Pneumocystis carinii. Loose stools for several days, but no fever, chills, hemoptysis, abdominal pain, or shortness of breath.
