I have similar history to yours... both hips replaced Jan 2017. I was 66 at the time and about 8 weeks post surgery began to have sharp thigh pain in left leg... 2 weeks later same kind of pain in right leg. one year 9 most later i am still having sharp pain in both legs, consistent but intermittent sometimes debilitating, always, every day painful to a degree. I've had every test i can think of with no conclusion. Diagnosed with mild osteoporosis of the lower spine. (not a painful condition) dr prescribing heavy duty drug for it - Forteo - i am skeptical but fairly desperate...hard to decide..... leaning towards trying it.... scared of side effects that may worsen situation... Right now i am able to push forward regardless of leg pain... extreme fatigue, flu like symptoms and headaches could make it impossible to have any type of reasonable life... keep hanging in there....
