Hi I am Dr.Kadhir,
These are characteristic features of flu, you need to take medicines like paracetamol
for headache, some times it is important to treat the severity of head ache as some of them can precipitate migraine
like symptoms (like what you have) with flu.
Antiseptic mouthwash should be goggled regularly at least 5 times a day until the sore throat
or any other antihistamine along with saline nasal drops will take care of your cold.
Antibiotics are usually not needed for viral flu , but it is better to take a throat swab if you are starting antibiotics.If you feel drowsy or unusually tired, having vomiting
, blurring of vision then it is better to go the doctor.
Thank you for the consultation in health care magic.
