Tetanus: True "lock jaw" is trismus, a pathological condition in which the mouth is held shut by sustained spasm of the masseter (jaw) muscle, often observed in cases of tetanus you may also be referring to "closed lock" a TMJ condition where the TMJ disc is locked out of position.

What doctor should I see about a roundish semi-soft lump under the skin just below the earlobe behind the jaw? Noticed it 3 days ago, and thought it was a non-itchy bug bite. It seems bigger now, and the area around there is achy. No other symptoms?
