I have visual & auditory sensitivity that when I hear high pitched sounds, it makes my right shoulder jerk or my body shakes for several minutes & when I hear a sudden loud sound, I fall down. Extreme visual stimuli, such as fireworks or flashing lights make my right shoulder jerk. I also have balance issues whereby I cannot be on a floating dock or boat without shaking & if I use an escalator or people mover, I have to keep walking on them or I shake. I can keep all of this from happening if I tilt my head to the right & sometimes even if I just close just my right eye. I also have a place at the base of the right side of my skull that when it is massaged, it will make my right shoulder jerk. My ANA level is high, Sjogren's is a possibility, & my neuro thinks I have some type of Multiple Connective Tissue Disorder. Could it be something that has affected a nerve in my neck? I have just noticed that if I stand with my feet together & my eyes closed, I start to shake but if I do it with my head tilted to the right, it doesn't happen. I think my warranty is up!
