I have severe tinnitus- often hearing sounds intracranially. how do i find out the cause and possibly the cure?

Tinnitus: Most commonly tinnitus is due to damage to the nerve that allows us to hear. There can be other causes such as benign rumors of that nerve or increased intracranial pressure. Recommend neurologic evaluation.

See doctor: Tinnitus can be caused by multiple causes starting from ear problems to medications, trauma, to hypertension, high cholesterol or tumours. Please consult your doctor .
