I am 28 years old. My neck has been hurting for over two years. When my neck hurts I get headaches on the back of my head. For about a year now, my rightshoulder blade has been hurting & so has my right hip. Now my knees feel weak & my left leg feels tight & at times numb. When my hip hurts it sometimes shoots a pain to myleft shoulder. I tend to feel dizzy as well. Could there be something wrong with my back? Or with my nervous system?
