where did this cramp in my neck come from?

Answer 1

It could be from the UK or may have been imported fom China as they are producing things at alarming and very inexpensive rates now.

Answer 2

The broken neck syndrome

The affected subject feels that he did not sleep right. He must have had some wild dream and somehow moved his pillow, and that is the believed reason for his pain in the neck. What is happening to him is convulsion in one of the two abductor muscles that connect the head with the collar bone. These muscles turn the head left and right, and also affect the up and down movement. The muscles run vertically in the posterolateral (back and sides) sections of the neck. When only one muscle is affected, the subject's head twists toward one side. When he tries to move his head the other way, he feels considerable pain at the collar bone. When both muscles are affected, the subject may feel global pain in his posterior lower neck and between and above his shoulder blades as he tries to bend his head down. The effects usually disappear within three days, but the next time the subject grinds his teeth during the sleep or chews hard food before going to bed, the same thing happens to him again.
The described symptoms may worsen after eating mercury-containing food (fish, shellfish) or chewing very hard food, or after a dental "restorative procedure" of the old fillings. The interaction between mercury amalgam and other dental metals (gold, steel, and titanium) commonly produces voltages of several volts and currents of several tens of microamperes. The voltages easily exceed the 0.7V firing potential of neurons, and erratic muscle jerking results. The subject's saliva and the metals in his mouth create a battery, and the electric current speeds up the release of mercury many times. The battery is "improved" by eating and drinking certain foods. Also temperature variations in the mouth affect the release of dental mercury into the body. In addition to the chemical impact, the electric currents produce their own harmful effects.

Much pain is from muscles below is an example of what may help (based on headaches).
Begin with a couple swigs of molasses or a couple of bananas daily - magnesium (which regulates many things in the body) and potassium (a needed building block for muscles).
Drink at least 1/2 gallons of water per day. Running a body low on water is like running a car low on oil is the analogy the head of neurology at UCDavis told my husband about 10 years ago.

Now to the cause - muscles - your back, neck shoulders and head have tender spots. They are knots in the fibers of the muscles called trigger points. It makes the muscles tight which makes them press on nerves and other things causing the pain.

The cure - start with a professional massage, you will also want to go back over any place you can get to 6-12 times per session up to 6 times per day rubbing (or lightly scratching on your head) every where that is tender until the knots go away. The place where the skull connects to the spine press up under the edge of the skull (to get to those muscles).
