Need help

8 months post OP Hamstring Autograft, was playing some light basketball pick up games and was moving laterally and tried to run forward. Knee felt a pop... but It was like more of a finger bone pop where theres bubbles in ur joint or something like that instead of a pop that tore my acl, Felt weak for an instant but can walk can stand on one leg without feeling imbalance but there is pain in my knee but mainly at the back of my knee. There is no new swelling present, did I just retear my acl or was it just some kind of hamstring sprain?
