Surgeon said he had to take cartilage out from my jaw?

Hi , got my all 4 of my wisdom teeth out 7 months, but about 4 days ago i got sharp pain in my lower jaw bone , the surgeon said he had to talk cartilage out from my jaw when he was doing the operation, but i hadn’t had any previous pain before hand, and now its starting to effect my other side of my bottom jaw, just wondering could it be a bone infection thanks
