With head and neck movement i get facial pressure, roof of mouth and bridge of nose just with head movement. what is the cause mri and scans are norma?

Facial pressure: 3 suggestions. 1 See an ENT for evaluation of your sinuses. 2 See Orthodontist for evaluation of your occlusion. 3 Be examined by, and have your MRI's evaluated by, an Oral Surgeon. We all come at identifying the cause of your problem from a different mind set/experience/training, so thinking outside the box may be fruitful.
