Sprained my mcl during football. i recovered and played the season. yesterday i felt popping in my knee same feeling from the first injury but not bad?

Knee mcl: Most of the time grade 1 or two MCL STRAINS heal very well such that it requires another new injury to become symptomatic again . The fact that B you could play that season would suggest that that is the case. Did the popping arise spontaneously or was it related to some recent B occurrence? Try rest , ice support , NSAIDs . If these r not helpful seek additional virtual input.
