My father had tympanoplasty 18 days ago. Today we returned home after 4 days of travel of which, 3.5 days were in train and last leg via bus. The road was rough on many parts and there were many sharp turns. There were some hilly areas as well. My father did complain of some discomfort in his ear during the journey. After reaching home, after some hours I noticed my father's ear was bleeding. It was bleeding through the cotton doctor had put in there and told us to remove after 20 days. Doctor had told us bus journey would be safe. Is there anything to worry?
