I get imbalance feeling/ not standing still with exertion/ activity, also by bending over, standing and working for sometime. It does not happen when I get up in the morning but as day goes by. It causes tiredness and I need to sit down. This goes away after sleeping/ taking rest. The day I am not active this does not happen. I have mild cervical spondylosis, and eardrum perforation from long time. Got bp checked by it is within normal range. What should be done.
