Very sore throat tried everything...?

Had a very sore throat for over a week now and I have barely been able to eat anythingbecause of it. I have tried everything (hot tea, gargling salt water, special throat spray, strepsils, chocolate, soluble aspirin...) but it has not done anything and it's just got worse until the point where it takes me about an hour to eat anything and it's so painful. What can I do?
