statin-induced myopathy: can vary from mild (with symptoms of muscle aches, symptoms usu-
ally abate rapidly after discontinuation of the statin, although occasionally up to 2 months may
be required) to severe (with rhabdomyolysis which can → nephropathy)

critical illness myopathy: Muscles not excitable with direct stimulation. EMG: low or normal CMAP with a normal SNAP. [[Muscle biopsy]]: abnormalities may range from Type II fiber atrophy to necrosis (severe necrosis may not recover)
