In young males like you this condition is quite rare unless you are an astronaut, isn't it? (edit: assuming you are male, sorry if mistaken)

  Vitamin D deficiency is common at higher latitudes (Bay Area is at the border) and as you get older. It can cause fatigue and aches. It is diagnosed through a simple blood screening.
