There is another thing you could try...

Magnesium comes now in a lotion you can rub on. This is very effective to reduce muscle tension, improve circulation and decrease pain.

When things are inflamed, often blood supply is reduced, so this lotion will open up the blood supply. (when oral supplements may fail).

This lotion is called Morton Epsom Lotion, and is available at low cost at Amazon and Walgreen's.

This is what the bottle looks like:

put only a small amount (a dime's diameter) on a fingertip and massage it into both sides of your neck below the ear and along the jaw, once a day. See if this helps. It will be absorbed thru the skin, and go right to your target area.

I'd get your B12 results in numbers. The ranges are still out of date, allowing levels that are quite low to be labeled "normal". The new low today is 400pg/ml.
So you could be low and your doctor is clueless about it calling it "normal".

Another question... can you inflate your Eustachian tubes easily?
Pinch your nose and gently blow against the closure and the tubes should snap open...they make various sounds depending on how swollen shut they are. When they stay closed too much due to sinus or other congestion, fluid backs up in the middle ear and presses on the ear drum. This is often one cause of vertigo/dizziness.

Your description of noises when swallowing could be these not functioning well.

Also meclizine and phenergan belong to the same chemical family, and could create side effects when used together.
The family is called "phenothiazines"--also called neuroleptics--and these can cause a side effect called tardive dyskinesia, which are tic-like spasms of the mouth, tongue and throat.

Meclizine and phenergan are more mild in this potential, but it is still possible.

I was looking around YouTube a few weeks ago and found a video by a young woman who claimed that one tablet of Reglan
set off her acute neck dystonia. Reglan is used for nausea in some ERs which is where she was dosed. She could talk fairly normally, but when she read aloud from any written form, she went into the most painful spasms... it was horrific to watch!
People can get all sorts of odd things like this poor gal had.

You might have a form of dystonia as well, and seeking a doctor who understands this difficult problem may reveal a treatment for it. (some dystonias are treated with carefully administered botox).

Do 1000mg of lysine a day to start. You can go up to 2000, if necessary. Typically it comes in 500mg tablets or capsules.
They are large tablets, so a capsule might be easier for you to swallow--you could empty it out into some food (applesauce or the like). Lysine prevents viruses from replicating and keeps them dormant. A diet high in arginine without the balance of lysine provokes viruses into becoming active.

Remember coffee and black tea are very acidic. If you decide to do the elimination of acid...you need to consider them as well.

The testing you had was mostly to identify organic tissue changes, lesions, tumors, etc. If doctors don't "see" anything on those, they tend to give up the search for a cause. Many of us on the Neuropathy forum here, have had that same experience.
