Degree understand your concerns went through your details. To answer your question, YES. Stress can be a cause for intense shoulder or neck pain. Stress triggers body to contract muscles and thereby chest, shoulder and neck muscles get agitated, triggering pain and tiredness. Light-headed feeling could be due to your obsession and anxiety. You need to consult a psychologist for psychotherapy treatment. If you require more of my help in this aspect, please use this URL. http
