Hi, dear I have gone through your question. I can understand your concern. You have headache, flu and blood in nostrils. You should go for complete blood count to check you platelet levels. If platelets are normal then nothing to worry. You may have some epistaxis. It is common problem and most of the time it is not serious. You should take drugs like paracetamol for headache and flu. Drink plenty of water orally. Don t worry just be relaxed. You will become normal within few days. Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health.
