Thank you so much for your kind replies.
I have an appointment for him on Oct 2nd at an ENT in our area.
I know that this is very unlikely, and people here have real issues and need help and I am probably just taking up space over worrying.
But something is not right. His voice sounds different, and he has a tender pain on one side of his windpipe area.
The doc said does not have an infection, and has not offered antibiotics.
