Feet Tingling: I suspect your neurologist ordered the spinal MRI to assess for spinal causes of your feet tingling - nerve impingement. Non-vertigo episodes of lightheadedness and dizziness lasting weeks could be related to several things: dehydrated/not enough water, low blood sugar, low blood (anemia), too low or too fast heart rate or heart dysfunction, and less likely brain-related but should be assessed.
