Causes of tinnitus include hearing loss due to advancing age,ear infections,wax in ears,ear trauma, loud noise exposure,meniere,s disease,acoustic neuroma and pulsatile tinnitus due to
pregnancy, anemia (lack of blood cells),
overactive thyroid,TMJ problems or tumors involving blood vessels near the ear.
It is very difficult to make a diagnosis without examination.So I feel that a consultation of an ENT specialist will be the best.
