I was playing badminton when I had to turn and dive and I got the outer side of the right knee wounded.(cement court). It is healing but today while I was climbing down stairs I experienced pain on the inner side of the knee. Can anyone explain what it is and is it safe to play if I experience pain while playing? I got the injury on 29th December, 2019 and I have not played badminton since then except for a few matches on the same day. It doesn't hurt while walking and I haven't tried running after the injury.
