What Could Whistling Sound, Crackling Neck, Irregular Bite Supressed By Touching Bones Behind Ear Suggest?

I have a whistling noise that can be controlled by touching my head, neck, face, nose and bones in collarbone, shoulders, and neck. I also hace a crackling in my neck and when I move it up or down I hear a cracking or snapping. I have a irregular bite and I can suppress the noise by touching the bones behind the ear. I was getting therapy for poor posture which helped with the noise. She worked on my c5 snd c6.
