right now I need to determine whether this is muscular or nerve related - if it's the latter, magnesium won't make a difference.
I'm very happy to hear you have confidence in your doctor and are following your doctor's recommendations.
However I am puzzled as to why you think that magnesium will not make a difference if it is muscular or nerve related.
"Magnesium is vital for the nervous system, muscle contraction"... "Magnesium is important to neuromuscular transmission...."

Magnesium Sulfate - Clinical Pharmacology
Magnesium is an important cofactor for enzymatic reactions and plays an important role in neurochemical transmission and muscular excitability.
As a nutritional adjunct in hyperalimentation, the precise mechanism of action for magnesium is uncertain. Early symptoms of hypomagnesemia (less than 1.5 mEq/L) may develop as early as three to four days or within weeks.
Predominant deficiency effects are neurological, e.g., muscle irritability, clonic twitching and tremors. Hypocalcemia and hypokalemia often follow low serum levels of magnesium. While there are large stores of magnesium present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral magnesium therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease."

"THE HEALTH OF THE NERVES
...one nutrient that recent research has found to be lacking in the diets of most people, and which lack may be the cause, of so much nervous illness, is magnesium. Information on, the essentiality of magnesium to the nerves was published by Penn and Loewenstein of Columbia University in
Science (January, 1966),...
Calms the Nerves
Magnesium works in other ways to preserve the health of the nervous system. By the twentieth century, doctors had learned that magnesium injections exert a depressant effect upon the nerves. In fact, one of the early uses of the mineral was to induce sleep. It is significant that hibernating animals have very high magnesium levels. Magnesium has also been shown effective in controlling convulsions, in pregnant women, epileptic seizures, and "the shakes" in alcoholics.
Yet one of the paradoxical effects of the mineral upon the nerves is that a magnesium-deficient person who takes magnesium feels more energetic than before, even though the mineral is a depressant and not a stimulant. Actually, magnesium relieves the nervous irritability and excessive energy that give rise to fatigue in the first place.
It should not be surprising, then, that when a person's magnesium level is subnormal, the nerves are unable to control such functions as muscle movement, respiration, and mental processes. Twitching, irregular heartbeat, irritability, and nervous fatigue are symptoms of what is frequently found to be magnesium depletion...
The fact is that, as new studies are published and new discoveries made,
it is becoming clearer and clearer that magnesium is one of the basic nutrients needed for a healthy nervous system and therefore almost any affliction in any part of the body might turn out to be actually an illness of the nerves that are involved because they are deficient in magnesium.
Most often, deficiency is simply a result of failure to obtain adequate magnesium from such dietary sources as wheat germ, cocoa, desiccated liver, eggs, green vegetables, soybeans, and almonds. In some instances, however, absorption of nutrients can be impaired by coexisting illness, such as an intestinal infection. In such an event, much of the ingested magnesium may be lost from the body....
A Host of Disorders
A case history presented in the
Archives of Neurology (June, 1965) by Dr. Robert Fishman of New York illustrates just how "inadequate dietary intake coupled with excess gastrointestinal loss" can lead to a host of nervous disorders....
in the October 1, 1966, issue of
The Lancet. It was the opinion of Dr. Caddell that magnesium deficiency was probably involved because of the essential role of magnesium in the biosynthesis and activation of thiamine pyrophosphate. . . . What she was really saying was that
sometimes a thiamine deficiency is caused by a deficiency of magnesium and therefore it will not be cured by the administration of thiamine alone.
Epilepsy is one good example of this. As far back as recorded history goes, the "falling disease" has been one of the great mysteries of medicine. While dozens and hundreds of other illnesses responded to investigation, epilepsy remained unexplained and untreatable by any known method.
It, is only within the past year that there has been published work revealing that epilepsy is accompanied by a lower than normal level of magnesium in the spinal fluid, and that administration of magnesium can be expected to bring about quick improvement.
It is a field that still requires much investigation, but
present indications are that deficient magnesium in the spine, and the subsequent effect on major nerves of the spine running to and from the brain, may be the actual cause of epilepsy. Later in this book we will see that this work emerging from the Hereford Clinic and Deaf Smith Research Foundation in Hereford, Texas, under the direction of Lewis B. Barnett, M.D., further establishes wide-range effects that magnesium nutrition has on the nervous system.
If additional evidence were needed that healthy nerves require magnesium, it would certainly be supplied by the recent investigational studies entering into the development of "memory pills" at the Abbott Laboratories in Chicago. Memory, of course, is one of the primary and most important functions of the human nervous system. And the stimulant to memory and other mental function that is being developed at Abbott has magnesium as its basis.
In other recent studies we have learned that the motor nerves--those that carry messages by electrical impulse from the brain to the muscles--are dependent on magnesium for the ability to conduct these minute electrical messages properly. Now we are learning that magnesium is equally important to the central nervous system (spinal cord), and to the brain itself.
Add to this the essentiality of the same mineral for hard healthy bones and teeth and for the functioning of many of our enzyme systems, and we believe it becomes perfectly clear that a person would have to be a fool to take any chance on not getting enough magnesium for even a single day."
