Do let us know how everything works out!
Thanks guys. I have been referred to a neurologist from my PCP to see if I can figure it out.
However, you have had a CT, and that is also used a great deal for tumors so unless it was tiny - your tumor was likely picked up.
There are nerve palsies that effect the face such as Bells Palsy and the like - but I would seek out a neurologist that treats nerve disorders and get EMGs and all to make sure that is not the issue as well.
Things that effect the nerves do not show up on any imaging.
Because there are so many things that can cause the symptoms you describe, the best thing would be an MRI. I have never had a CT for my tumors. I also belong to a forum for my type of brain tumor (meningioma). Everyone on there gets regular MRIs, and many of the people have the same phobia you do. I think I have read that some hospitals will do MRIs with sedation. You may want to consider it. I have also heard of people doing open MRI while tracking brain tumors, although I think the resolution isn't as good.
