What could be causing my gradual onset of bad vertigo, headache, and i frequent sharp pains deep in my ear. some pain also on right side neck. ?

Vertigo and pain: If you haven't seen your doctor about these symptoms, call for appointment now or consider seeing a Neurologist. The underlying cause of your symptoms could be something simple such as an ear or sinus infection or could be very serious such as a tumor. Rule out the simple causes first, if no better, look further. Do not ignore these symptoms.
