Hi, Thanks for using HCM.
Persistent sore throat
could be due to irritation which could be from nose as a postnasal drip or gastro oesophageal reflux. Better to get evaluated for that by a ENT specialist
Now sputum production shows bacterial infection. you need to take antibiotic treatment, tab. azithromycin
for 5 days.and anti inflammatory to reduce inflammation, tab. paracetamol
.antihistamines to reduce congestion.
Warm salt water gargling 3 to 4 times a day.
Steam inhalation, gives you more symptomatic relief.
Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
