(Concern) Lately, my throat has been feeling blocked and there's a strange smell coming from my nose.

It has been about two weeks since my throat became blocked and I developed a hoarse voice. However, it hasn't gotten better. Also, I have a strange symptom where I smell something like rubber burning inside my nose. It's not continuous, but I feel it intermittently. I don't have a fever or body aches, so I thought it was just a temporary symptom and didn't go to the hospital. But it hasn't improved. Does anyone else have similar symptoms?
