Swelled nerve, mandible/jaw/inner cheek.

In my right inner cheek i found in the very lower part there's a kind of bulging nerve, itches slightly when pressed, why is it happening? Also in my right lower mandible i found there i get soreness sometime on the nerve present there.. why is it happening? Is it any AVM? Area for inner cheek marked in yellow colour circle and for mandible area marked in purple/red where the pain/soreness occurs on the nerve. The inner cheek nerve that i talked about is only found in right side, in left side I searched couldn't find that bulging as it is in right. When seen in photo it's not visible when touched it feels bulging. Please help me. I touched that pink circle area more and seems it became more sore so m avoiding touching that area, but why is it happening, please help..
