Throat feels uncomfortable at bottom of throat, I have constant mucas at back of throat and the right side of my neck aches sometimes?

Viral URI. Most likely early symptoms of viral infection or Upper respiratory Infection. These can manifest in many different ways, including runny nose, increased mucous production, sore throat and/or ear pain. Treat symptoms with OTC throat lozenges. Should run usual course in 5-6 days. If symptoms worsen or last longer than 7 to 10 days, see your doctor.
