Hello dear, The symptoms as mentioned in your post can be attributed to acute exacerbation of Sinusitis. Investigations like complete blood count & X-ray of paranasal sinus will be helpful in clinching the diagnosis. As your nasal mucosa is congested & the olfactory component is deranged, you are not able to appreciate the taste of food. Management includes: 1. Steam inhalation. 2. Analgesics like paracetamol 3. Nasal decongestant drops. 4. Antibiotics depending upon culture & sensitivity as advised by your Doctor. Kindly continue them. 5. Antihistamine preparations can also be used to provide symptomatic relief. 6. Maintain adequate hydration & a healthy balance diet. 7. Also make sure that you are well protected from cold, dust & other allergens. Your symptoms will be relieved with this. Wish you good health & a speedy recovery. Take care.
