My mother is 52 years old having weight of around 95 kgs. She is having pain in her left leg on knee. She use to exercise a lot before. Bt having no relief she discontinued. Now she use to go fr walk in the morning for around an hour. And she does all her home work. Making food, cleaning the house. We are also consulting our family doctor. But there is no such relief in her legs. And now there is a slight pain in her right leg also. So please guide me a good treatment.
