Jawbone hurts, please help?

Hello, first would like to say that a dentist once told me that I am one of the few people to never develop wisdom teeth and I never will, but instead I was born with empty pockets inside my jawbone where i would ume the root of the wisdom teeth would be. I do occasionally develop the symptoms of regular wisdom tooth intrusion. Now heres my concern. On my lower Jaw, half way between the ear and chin where the jawbone slopes up, I have a pit and crease that go all the way around my jaw bone, on both sides, the pit and crease are obvious to the touch, the crease feels like my jawbone was once two separate pieces or broken, thought it was never broken. oddly enough the jawbone abnormality lines up with my absent wisdom teeth locations. On my left side the pit is deeper and has been hurting for about 4-5 yrs on and off. when I was 12 I had a abnormally large molar extracted which left a large gap and hole, could this possible be due to dry socket, my dentist then didnt warn me about that possibility but i have long suspected it could be part of the reason. besides the occasional cavity pain, i dont have any other pains. Has anyone heard of similar cases? Thank you
