My sister coughed up a object with blood and mucous attached. Went to a pulmonologist and found 5 nodules on chest x -ray, thought posssibly hystoplasmosis. Sent for barium swallow, told severe reflux(no symptoms) and 1/4 blockage throat, esophageal hernia and something pressing against throat that they could no tell. Sending to ENT, what are your thoughts?
