Ever since New Years Eve/ Day my throat has felt flemmy. It all started when I was driving home from wal-mart. I felt sick but I didnt end up getting sick. Instead, my throat felt all flemmy and my throat was congested for a day. To this day my throat still feels slitely flemmy or gaggy when I talk but my chest is now fine. My dad says that my throat is probably still feeling the way it is because I'm hitting puberty and my voice is preparing to get deeper. What do you think?
