Erratic Mouse Lag In-Game

I have had Minecraft since 2013 and have loved it since then. Up until recently I have been receiving this problem. I would join a Single/Multi player game and I would walk a little. When I looked around the mouse, the in-game character would spin around, as if I was spinning my mouse around. I tried to set the priority for Minecraft to High, which would eliminate the spinning but would instead cause insane mouse lag.

I have tried updating my drivers, uninstalling Minecraft, and restarting my PC.
