I always get this sore throat once a year that will last for over a month and makes chest feel slightly tight when I slant foward?

Chest tightness. Pleurisy is an inflammation of the pleura, which is a double-layered membrane that covers the lungs separating it from the rib cage. Viral infection is a common cause. This is self-limited and you treat the symptom. Other causes of chest tightness could be related to muscular pain from coughing. If pain persists, see your physician.
