My throat feels like it's getting pressed on, has difficulty swallowing, especially when i look down or lay down on pillow face up. started snoring.

See your doc: Any time you're experiencing difficulty swallowing (dysphagia), it's absolutely something that should get checked by a physician. At the least, you'd benefit from a full history of the problem and a few imaging studies, and it could ultimately result in endoscopy to view if there are any anatomical issues. Short answer, see the doc
