For the past 4 weeks I have been feeling off balance and "spaced out". I do not feel dizzy or lightheaded. I had this same feeling about 6 months ago, saw my doctor and took sudafed at his recommendation. Within 4 days I was better. This time, however, I am still feeling constantly off balance and spaced out. I have seen my doctor once and one of his colleagues. Both did the quick nuerologic test in their offices (touch your finger to my nose and let me see you stand on one foot, etc.) and then said that it was probably labrynthitis. I asked my doctor for an MRI (I fear Parkinson's, brain tumor, etc.) but he said my exam did not warrant an MRI. Can Labrynthitis cause these types of symptoms to last 4 weeks? And why do I feel spaced out??? Please help!
