So for context I tore my left ACL 3 years ago and had surgery for it and been fine ever since then but tore my right ACL in January and had surgery in March, but been feeling pain and discomfort in my left knee ( the old acl surgical knee), No pop or sharp pain or anything, just random pain in different parts around the kneecap, with some puffiness not big at all, and like clicking on every step or when I bend and straighten my knee.
Is that because I’m relying heavily on that knee? Or is it because I used to be active and had to not move for a few weeks? Or both?
Just hoping its not a retear or something major.

Thanks in advance for any helpful info.
