Throat front tightness. What to do.

Hello, I am experiancing some kind of tightness in the front of the throat since a few ways which is not going away. To start, on 5th March, 2020, got wet riding in the rain for long time with my visor open. After a week, I had cold and fever, which lasted for few days, and was gone. Still I had kind of itchy throat and soar throat, and feeling to clear my throat consistently through out. That lasted for around a 7-10 days, which went off, and then this tightness in front of the throat came. Around 15 April. Last week, i.e 22 April,  I saw white dots in my tonsils area and reddish bumps back of my throat, so I consulted a doctor online, he gave me some medicines. Now the throat is okey with the tonsil stones and all are gone , but tightness in outer throat is still there like a rubber band tied to my throat, which is very uncomfortable feeling. There is no lump feeling as well. To add, I was also under stress for the whole march month. I am clueless what to do.
