Hi friends, I am writing a problem that my mother has been suffering for nearly 2 yrs now. She has burning sensation in her legs starting from knees to some region below it. I have taken her to the best of the orthopedic doctors in my region (Hyderabad). They never seem to point out the exact problem, the common answers are age, bones getting weaker. But none of their answers could satisfy me. My mother can not sleep at nights neither she can sit pleasantly in day. She is extremely disappointed because of this and me too. It would be great if any one point of the causes and remedy for this. I would be indebted to them for my life.
