Sore throat. Far no covid case reported.

I had sore throat with mild (99) fever. I took Cheston cold (3days) and Cofsil. Sore throat was almost recovered, but I developed right ear congestion. Then after ent consultation I took Augmentin 625 Dou tab (5days) and SignoFlam tab(4days). My sore throat was recovered but ear congestion was still there. Last three days, I didn't take any medicine after completing the antibiotics course. Now, sore throat is back again with mild cough but no fever so far. Ear congestion seems to be improving,  I don't feel any pain in the ear. But feel mild body/face pain.  Nose congestion is very mild, which is normal for me. No breathing issue. Altogether, it's 20 days I have these issues. Any suggestion for complete recovery of sore throat will be appreciated. In my city so far no covid case reported.
