I have so much mucous in my throat and what it is and how to get rid of it?

May be strep, etc.: Nose and throat symptoms can be from cold viruses, strep throat, allergies, irritants, stomach acid reflux, etc... Sometimes, it can be difficult to tell what the cause is. If symptoms only last 1-3 days, it's more likely allergies, irritation, or a mild cold. Doctors have rapid 5-minute tests for strep throat, so a primary care doctor can examine and diagnose what the cause most likely is.
