It started 3 days ago I woke up and had a pain in my throat when I swallowed, I figured it was nothing because I was sleeping with my mouth open because I was recovering from a slight cold, so I thought it was either dry or just drainage, though it was a little suspicious because it was only on one side. I wouldn't be worried but its happened for three days, it hurts the most when I would laugh, I'm asking because I've had a lot of strep throat and the doctors have considered taking my tonsil's out but never did.
