Feeling like scratch down side of throat with ear irritation, couple days later led to productive cough with yellow/green mucous. Raw feeling. Strep?

Dr. can check throat. Throat symptoms can be from a strep throat infection (antibiotics are needed), a cold or other virus (antibiotics usually not used), allergies or irritants, sinusitis, stomach reflux when asleep, etc... Usually, a person sees the doctor if the throat is bothersome, recurrent, or doesn't go away quickly (mainly to check for strep).
