[|Human|] Nearly four months ago I developed a bad dose of flu. Since then I have not been able to smell or taste anything. I cannot take decongestant tablets because I have hypertension. Could this be permanent or is there still a low grade infection present which might benefit from antibiotics
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Your symptoms seem to be related to loss of smell. This is a common complication of flue infection, caused by the dysfunction of smell receptor cells. The lack of taste, may be related to the smell dysfunction (smelling plays a big role in the taste of food). Another diagnosis to consider would be chronic sinus infection. A sinus X-ray study would help to exclude that. This may be just a temporary dysfunction. I would recommend you to consult with a neurologist for a careful physical exam. Some vitamins would be helpful. Best wishes,
