Is this just going to be a sore throat or will it get worse?

Starting yesterday, I got a sore throat. It wasn't really bad. I went to sleep and found myself worse (I have been coughing up phlegm and the sore throat is worse.) In order to soothe it for a few seconds is to drink. Also, it seems every year now, I get something that is like Bronchitis. Is the throat and phlegm just the beginning of something serious, or should I be fine? Thanks.
