Three years agoI had surgery to remove a sub-sternal goiter. The surgery was difficult and my head and neck were in a hyperextended position for over 3 hours. The surgeon had trouble removing the goiter for several reasons..anatomy, scar tissue from a previous thyroid operation and the position of my vocal chord nerve in relationship to the goiter. I had a raspy voice after surgery, but that improved in time. Immediately after the surgery I felt heavy headed and dizzy. I had unusual visual patterns and had trouble with my balance. Three weeks later I developed tremors and had extreme head and neck pain. Not like an ordinary headache, more like a pulling, vice-like sensation. I went through balance disorder physical therapy and have been prescribed many different medications, none of which helped. Over time my symptoms have lessened, but everyday is still a battle. This year I had a nerve conduction study on my neck and shoulders which showed impressive motor unit activity and was I diagnosed with dystonia and am receiving botox injections in my neck and shoulders. I continue to have chronic sensations of pressure on the sides of my head due to the dystonia. Botox helps to an extent, but not completely. My neurologist feels that I suffered some sort of trauma during the surgery, but does not understand why I have tremors throughout my body. I have them in my head and shoulders, both arms, back, abdomen and legs. It feels like there is a motor running constantly in my abdomen and chest. Could my vagus nerve have been compromised during this operation and be causing these tremors? I feel in my gut that all of this is connected, but the puzzle hasn't be completely solved. Is there any test to determine the health of the vagus nerve? Can you think of any reason why these tremors and spasms have persisted for over three year? All MRI's of head and spine were normal.
