Hi Doctor, This Is Srikanth Reddy And My Age Is

Hi doctor, this is srikanth reddy and my age is 24.I am feeling some kind of uneasiness in my legs.I have this problem for 2-3 years. But it was not very often then.But recently I have been suffering with it most of the times when I walk, sit in a place for long time and run. I have consulted a doctor who could not help it. He said calcium is low.but i feel good with remaining parts..kindly suggest me.
