How can I deal with constant lightheadedness, periodic vertigo and the need to hold into objects to stay upright?
The symptoms you describe may not be due to MS. I would suggest that you bring up these complaints with you physician soon so she/he can examine you (including checking your vital signs in different positions: laying down, sitting, and standing up) in order to discern what is the cause. In the meantime, keep yourself hydrated. Without knowing the cause of your symptoms, it is not possible to give specific recommendations.
