 [ Symptoms ] my husband has been coughing up phlegm with bright red blood [ Disease ] hi coughing up of blood can be from either upper digestive tract or respiratory tract and it needs a thorough evaluation to rule out the exact cause yes irritation or ulceration of the oesophagus can be a cause as there have been repeated episodes of coughing blood therefore you need to consult a physician soon and get evaluations like endoscopy laryngoscopy chest x ray etc done for diagnosis hope this helps
