You know, I wonder how many of us have whackiness going on in our brain stems?

A lot of the sensory stuff to do with the face/senses such as taste and smell point back to brain stem issues/lesions etc.

Maybe not all of us have been diagnosed with MS.. but lesions can occur with other conditions as well. Does TN in itself cause lesions or result in? I haven't done much reading on TN apart from MS, so you'll have to teach me a bit.

When my TN flares, the taste gets altered. That much is for sure. When taste gets altered, often smell does as well.

Marijuana is 1 smell that I can relate to smelling when it's not actually present. With MS we often refer to these smells that are not actually there as 'phantom smells'. It's a recognized phenomenon .
