Well to clear some things up...let's learn about the cranial nerves!

The nerve that controls your tongue is the Cranial Nerve VII or CNVII.

The nerve that controls the motor functions in your face is the CNXII

The nerve that is responsible for facial sensation (and some motor) is the CNV of which the trigeminal nerve is part of.

And finally there is The glossopharyngeal and vagus nerves (CNIX &CNX) which are responsible for a multitude of functions...including taste, larynx, gag reflex etc...

Here is an excerpt from some light reading I did before I had my facial nerve graft last year that may help ease your mind.

"Somatic sensation
The glossopharyngeal and vagus nerves (along with the facial nerve) supply tiny sensory branches to the external auditory canal. This extensive overlap (which also includes some contributions from the trigeminal nerve and the 2nd cervical nerve) precludes detecting loss of sensation caused by lesions of any one of these nerves. However, pain in the ear may be a prominent early symptom of irritation of any one of these cranial nerves. If the vagus or glossopharyngeal nerve is involved, the pain often extends into the pharyngeal region, helping to differentiate from the pain of seventh-nerve irritation (which would be confined to the ear and mastoid region)."

You have a lesion on your tongue dear, realize that these nerves have a lot of overlap and disruption of one can cause issues in another.

Hope that helps Breath and believe...and don't forget my advice on vaporizing!
