Sorry if I sound rude but if the Flu had started to pass and your temperature had reduced what did you expect him to do? Flu is a virus so no antibiotics are required and are not at all beneficial. Doctors often see 40+ patients a day, for 10 minute appointments. Many people who really really need a doctor often have to wait days for an appointment, there are also patients with major problems which can't be dealt with easily in 10 minutes. If I was him and it was obvious that I could be of no help and I knew that I had another 30 patients to get through then I would have said the same, paracetomol (if still fever/aches), fluids, rest. He's there to do a job, although I do feel he should be courteous. If you were getting worse then it'd be a different story. Sorry if that sounds insensitive. I really hope you feel better soon.
