Last july, I had thyroidectomy surgery every since my blood pressure is out of control until the doctor put me on blood pressure medication, she said my headache is from blood pressure. Back in December the freezer door fell on my head I got a ct scan and they found nothing wrong.my headache started in late feburday tingly and contraction in my head, when I get a servere pain I get pressure in face jaw and ears I do have post nasl drip as well. my doctor still insisted is blood pressure.Do you think my blood vessel got nerve damage?
