Thanks for your query at HCM! You seem to have acquired viral (RSV, Influenza, Parainfluenza, adenovirus, mumps,etc) or bacterial (Streptococcus Group B, Corynebacterium, Pneumococcus,etc) infection of respiratory tract. I suggest you get the complete haemogram and throat swab and blood culture tested for gram stain and culture sensitivity for aerobic/anaerobic bacteria. Get treated based on your tests. Viral infections are self-limiting but you can start treatment to prevent secondary complications with bacterial infections. You can start analgaesics, anti-inflammatory with serratiopeptidase, anti-allergic and antibiotics(azithromycin/erythromycin) which would require prescription from a local doctor. Do gargles with chlorhexidine wash for 6-8 times/day. Hope I was helpful. Take care! Take multimineral/multivitamins also
