You might need to have the sugery. Mine never hurt until it erupted but I actually use my wisdom tooth. If yours is fully grown it will stop. If you don't have a crowded mouth, take it out.
It's more of a minor irritation right now, I get caker sores all the time so I'm used to it, but it's never hurt for several days. if it can stop by itself I rather not use that money since I don't have any sort of insurance
