Levels of groin strain: what they mean

A mild strain may cause local soreness during running, cutting, or squeezing the knees, with little loss of strength. A partial tear can produce clearer pain, weakness, bruising, or difficulty walking and changing direction. A severe injury may involve marked weakness, a sudden pop, substantial bruising, or inability to continue the activity. These labels are guides rather than a diagnosis made from pain alone.

The adductor muscles on the inner thigh are frequent sites, but hip, abdominal, and tendon problems can also cause similar symptoms. An examination compares strength, range of motion, walking, and sport-specific tasks. [Groin Pain](/symptoms/groin-pain/) can have more than one cause.

Stop the movement that triggers pain and keep gentle, comfortable activity if walking is manageable. Early care may include relative rest, a protected range of motion, and cold applied through a cloth. Do not use pain relief to test whether you can sprint or kick. As symptoms settle, a clinician can progress inner-thigh strengthening, trunk control, balance, and running drills.

[Exercise Therapy](/treatments/physiotherapy-and-rehabilitation/exercise-therapy/) can build capacity gradually. A [Sports Physiotherapy](/treatments/physiotherapy-and-rehabilitation/sports-physiotherapy/) assessment is useful when the injury is linked to training, competition, or repeated episodes.

Seek prompt assessment after a forceful injury, audible pop, rapid swelling or bruising, marked weakness, or difficulty taking normal steps. Urgent care is appropriate for severe pain with a visibly deformed area, inability to bear weight, numbness, or groin pain with abdominal or testicular symptoms. Symptoms that fail to improve with sensible activity reduction also deserve review.

Which muscle or tendon is involved? What activity level is safe today? Which strength and movement tests will guide progression? What milestones should I meet before sprinting, changing direction, or returning to matches?
