Weird spot on neck

[Spacehawk]

Hello, my garter snake here has recently developed something on his neck behind his mouth. I know these pics arent great i just took them this morning but i can try to get better ones when i get home tonight... anyways this is new to him, ive had him for about a year and this wasnt there, i cant tell if its a scab maybe he hurt himself but its more pinkish and i was worried about it being something more serious than a scab, i dont know of any reptile vets in town, if anyone has seen this before i appreciate all input or suggestions.... thanks
