I suffered a mild concussion in July 2007 and am still currently experiencing symptoms of dizziness, inability to concentrate, sensitivity to light/noise, and the primary symptom (that seems to be the most debilitating) is a sensation that I am always in a 'dream'. This PCS has now persisted for 5 months and although symptoms have SOMEWHAT diminished, I am concerned with the time it is taking to get better. I am currently doing my masters in virology in England and am finding it difficult to concentrate and focus. I must add that I am a very active individual and have been running since the incident... all the neurologists that I spoke with did not advise against mild physical activity and actually thought it might help with my balance issues. Do you think this activity may be preventing my recovery or could I have done damage that cannot be counteracted by being physically active? My symptoms do not seem to be exacerbated with physical activity. Although I must add then when I am extra tired, or stressed my 'dreaminess' is intensified as well as my dizziness AND my hands tremble. Is there ANYTHING I can do to ensure that I do get better? I am willing to go to any lengths to aid in my recovery as I am SO scared that I may never get better... living in this 'dream' for 5 months is absolute torture and I am desperate for any advice you may have. Thanks very much.
