i didn't know where to post it so i did it here as it seems the most relevant. i have been playing badminton for a couple years now. A problem i am having is when i rotate my wrist (move it in a circle) it always makes a weird sound: the best i can describe it as cracking your knuckles but multiple "cracks" as i rotate my wrist. Also, when i do push-ups, when bending the elbow down, it also makes a similar sound described above. This problem has only started after i started to play badminton. This effect doesn't cause pain but it doesn't seem to be normal. Can someone help me with this problem? - i asked a friend and he said that its related to the overuse of a muscle and the tendons are wearing down ??
