age 50, both at night and when walking for any length of time hips ache. also knees seem stiff. occasional lower back pain and sleep starts. insomnia and nocturia. main bread winner and work varies between sitting, standig bending, squatting and pushing /pulling large items. lack of sleep leaves me tired and am afraid of causing a car accident while driving. no other exercisr though seem to work harder at home than work currently clearing two rooms of hoarded junk some of which is awkward in shape or heavy.vegetarian so fish oil/green lipped mussel out and eat nuts 4days a week so doubt lack magnesium.stiffness and deep aches not sharp pain.also sleep starts can be quite violent spasms of head/neck shakes. any ideas? sunny.
