For the past monthy I have had headaches , light headedness , insomnia , numb upper lip and a teeth chatter . I feel that all this will never go away . I have had a MRI , lumbar punture , blood tests , and ct scans all negitive . I have tried all types of sleep aids from Ambein , valerin root , teas , and melatonin ( which is the only one that has worked slightly ). Could somebody please tell me that I'm not the only one with this problem.
