Hey, thanks for the response jayhybrid. Yeah, I don't think its hyperacusis. That's an over-sensitivity to sounds. I mistook fullness for tightness. And, the perceived sounds (snapping) is muscle/tendon movements rather than tinnitus (ringing). It's probable that I'm suffering from chronic tension headaches along with Major Depression and Anxiety. It's really tough trying to articulate symptoms that are so vague. But, I think I'm finally on the right track. Thanks again! Take care.
