How long does it usually take for a groin muscle injury to heal?

Depends on injury: The healing time of a muscle strain or "groin pull" depends on the severity of the injury. If you see bruising along the course of the muscles it will take longer. Labral tears of the hip can cause groin pain; so if not improving within 4-6 weeks that should be considered. Step one-ice the area to minimize the zone of injury step 2-restore pain free flexibility, strength then sport specific ex.

6-8 weeks: Groin injuries can take 6-8 weeks to heal if you tore a muscle or tendon. Less if just strained.
