Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have depression and buzzing sensation in head which can be caused by many factors like stress , temporomandibular joint problem , wisdom tooth , cervical spondolysis and increase blood pressure. Main cause of tinnitus is either overall increase in blood pressure or local increase in blood pressure do to blood vessel dysfunction.
Buzzing sensation or tinnitus can also cause by psychological problem like stress and anxiety. I would suggest you to
consult ENT specialist for proper examination . Doctor may order certain test like audiometry , CT scan ,MRI , low and high pitched ringing to rule out conditions like hearing loss , exposure to loud noises , earwax buildup , middle
ear infection.
Doctor may also refer you to
psychiatrist .Doctor may remove wax , prescribe antibiotics along with anti inflammatory and supplement like
ginkgo biloba . For now do mind relaxing exercises like meditation . Doctor may also refer you to
dentist for wisdom tooth problem . Meditation and yoga will be helpful.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
