just exactly 'where" on a "neck bone" is this located and is this a hard or soft type of 'bulge? the exacting location, along with the consistancy of that bulge just really DOES matter here. the more specific you can be in descrtibing this the better? but at the very LEAST at this point, simply seeing your primary for the eval and basic c spine series films would be a great starting point. what actually would show up on the x rays would help determine exacxtly what this bulge even consists of at this stage.
are you "feeling' anything at all that would be considered a 'symptom'(pain, nurabness tingling? stuff like that? or problems with ANY fingers?)? that matters too. Marcia
