I would recommend putting some moisture in the air by using a humidifier. The moisture will help keep your throat moist and help the sore throat go away sooner.
Also take some cough drops such as Halls, and maybe even gargle some warm salt water and drink some warm tea with honey in the tea.
The honey in the tea will help lubricate your throat and help to keep your throat from hurting as much.
The sore throat should stop hurting within 5 days and be fully gone within 10 days.
