Priorities for further investigation would be a thorough history, physical and neurological examination. A neurological examination should aim to detect any specific deficits, and distinguish muscle weakness from neurological disease (e.g. by careful assessment of proprioceptive responses). Initial screening blood tests should include serum biochemistry (including CK, urea, creatinine, calcium, phosphate, sodium, potassium, thyroxine) and urinalysis.
