Understandable: There are many other possibilities for your symptoms. It would be unusual for a tumor to cause symptoms that resolve by themselves without treatment. Seeing a neurologist is the way to go as a good exam and further tests as needed should help clarifying the origin for your symptoms.

Determine cause: Please see an acute care center or the Emergency room. You may be experiencing a stroke,heart attack or another serious condition. Please seek medical care.
