Is she taking statins?
Did she get vaccines?
The elderly sometimes can no longer make certain nutrients due to aging.
CoQ-10 (depleted by statins too)
Acetyl carnitine especially enables mitochondria to work better.
This is my mitochondria thread from PN:
It is becoming more apparent that mito damage may cause many symptoms as we age. Antibiotics damage mitochondria, for example.
My impression of Polymyalgia is that it is more a descriptive
disorder, like Fibromyalgia.
Long term use of steroids in high dose in the elderly are highly problematic for bone density and other reasons. They also cause muscle weakness.
I'd try a good quality aqueous CoQ-10 product and see if the muscles improve. Muscles and the heart use large amounts of CoQ-10, and if it is low, then pain, stiffness and loss of strength happen.
Q-gel is one quality form. If using this only 100mg a day is needed. Another which I am trialing so far with good results, is
Qunol ubiquinol, the activated form. Costco had it on sale recently and it seems to work well for me.
Prices for this newer more soluble form are coming down recently so they are more affordable.
So I'd start with CoQ-10 in some form first. YOu can PM me with further questions any time.
