Hello,
Thank you for using DoctorSpring.com
You are suffering from sinus infection, loss of smell and taste sensation for 2 months. Your main concern is taste. Our perception of food is flavour which is smell of food n taste. So many time loss of smell will cause change in taste. It ll improve with time.
As you CT scan is almost normal so you have limited sinus disease. Still examination by ent specialist with nasal endoscope will give some more information. If facility availabe a test for smell can be done.
After completing course of antibiotic you can conitinue steroid nasal spray for 3 months.
Hope this helps
