I listen a clicking sound from my right side of jaw when i open my mouth and when I shake my head towards back side. My right jaw deviates towards left side and My jaw muscles become very tightened sometimes. Also I have neck pain, upper back pain and sometimes I feel breathing problem. When i do posture related exercises I feel better than before and i listen lesser numbers of clicking sound that time. Is postural problem related to my jaw problem? I am really going through very very tough time. Please don't ignore it. please help me and tell me what should I do at that time.
