It started about a few months ago and whenever I move my jaw from side to side, I can hear rustling and little cracks in my ears. First, it was only my left ear, where the jaw bone and the ear connect. Now, unintentionally, I often crack that area as if I were cracking my fingers, so it makes a large cracking sound. After cracking it, it feels a bit loosened although I can still hear tiny cracks. Sometimes it sounds like "wet" cracks, in both my ears. In the beginning it wasn't causing me any pain, although now I feel as if some of the headaches I get are because of it and it is generally sore around ears at times.

Is this something to worry about? Should I stop cracking my ears?
