It started since school days(2006-07), my knees used to swell and pain. I had few allopathic & ayurvedic medications afterwards and it stopped. But it has started again this year, it happens mostly when it is utilised a bit excessively, like playing badminton or climbing stairs. Just to note, my aunt has arthritis and mother is also facing joints pain. The pain increases in winters or if the knees are undergone any shock in the day to day activities, like minor jumping without proper shoes.
