Helo doctor. Its regarding to choking . My co usin was having peanuts and that suddenly got stucked in his windpipe that made much difficulty in breathing. He wasn't able to breathe for a moment. And after coughing he was as fine. Breathing normally. But his concern is eventhough he is able to breathe properly, swallow properly he thinks whether the peanut has got stucked in his lungs and he is afraid whether that would cause pneumonia . So what are the suggestions ??? Do I need to get a scanning for that???
