I am 29 years old. I have a pulling sensation on the right side of my head which spans through my ears and jaw. I have this for more than 2 years now. Although the frequency and intensity of the sensation is lowering over time but it's not completely going. No pain just some intermittent band like feeling. I have a cervical spine MRI done for this which is normal. My B12, vit D, TSH & CBC reports are normal. What could this be?
