Sound then lockingMy jaw clicked before, and now my mouth does not open well. Could it be a disc problem?
It is possible, but clicking followed by limited opening is not always a disc problem. Joint catching and muscle guarding should be separated before deciding next steps.

DeviationMy jaw shifts to one side when I open. Is that a TMJ problem?
It can be related, but mild asymmetry alone does not prove a problem. Pain, clicking, catching, limited opening, and the direction of deviation should be checked together.
