Talk to ENT on Sore Throat With Painful Enxtreme Cough And Green Phlegm Blocking Nose(almost Every Hour)

I have had a sore throat for 2 days and it is causing me a hard cough with pain, I can't pronounce words correctly. Phlegm is an extreme green fluid that is blocking the nose from breathing. Kindly suggest me medicine to take and other precautions as asking real doctors is better than self remedies or medical store suggestions
