I started a Alternative therapies info thread - PEMF, LLLT, Acupuncture , etc.
If anyone has an interest in or tried any of these feel free to post about it.

If it is on both sides I think it is less likely that it is caused by mecahnical damage, since the cranial nerves innervates only one side of the head.

The cervical issues could affect the production of saliva and tears (the sympathetic pathways), but I doubt it is causing your sensory symptoms.
I guess it is more likely that dryness would be caused by over productive sympathetic system or week parasympathetic, or some type of inflammation in the glands, then from a mechanical damage in the cervical spine.

I took some neuroanatomy courses but I am not a physician, so....

I had the trigeminal neuralgia many years ago, luckily it gradually improved and disappered within a few months. I had severe pain attacks on the right side of my face, it felt like all the teeth at that side ache, the ear and the right side of the throat ached like having an infection, the right eye, temple, scalp....
There were many pain attacks each day and touching the area, wind, swollowing food etc were triggers.
Since then sometimes I still feel symptoms in the head like yours, tingling, electric shock, numbness, it comes and goes, but usuallly it is only on one side of the face.
It is pretty wierd to feel the distinct borders... half nose is tingling.... electric shock/reduced sensation only on the upper right lip when putting a moisturizing cream... electric shock when touching the right eye brow but not the left... sensitivity on one side of the scalp when combing my hair...

I don't feel these distinct borders with the numbness, tingling, burning etc in the rest of the body that were caused by the SFN

Again, thank you so much for all this. I'm learning quite a lot from a number of people on here and I'm grateful for that. My and my physicians' suspicion is also that the mechanic issues are not causing any symptoms, certainly not any of the main or pronounced ones, and you seem to agree. Yes, mine are all over, say my right eye right now (twitching) and my left temple (tingling).

I'm sorry you had such a miserable condition but glad to hear it has gone away. It sounds truly miserable, not that anything any of us have is a walk in the park! I was half asleep the other night and I think I had a very sharp pain go through my jaw/teeth, but I couldn't be sure and it hasn't happened since, so I've ignored it. I don't have issues when chewing. I do only get a sharp electric current, like shocking sensation, only on my right side, from rear cheek or eye to nose, but it's very rare. I wonder what that is. It never happens on my right side. Who knows though. After a certain point I just throw my hands up and say the body is a strange thing and I can try my best to heal myself holistically.

Thanks again for all this information!

Thought perhaps I should look into trigeminal neuralgia, symptoms, causes and treatment, in case some of my symptoms, say that shop can be caused by it. How does it come about, for example, I wonder. Is it mechanical or damage of some other sort, etc. Not sure about any of all this, but perhaps worth looking into.

what were your values with skin biopsy if i may ask

If you're asking for mine, I believe it was 3.3 mm, whereas the lower limit was 5.2 or .3
