A knot in the groin muscle

The groin contains muscles that bring the leg inward and help stabilise the pelvis. A sudden sprint, change of direction, kicking, heavy exercise, or reduced hip movement can irritate these tissues and create a tender, tight area. Pain may also come from the hip joint, abdominal wall, tendon, lower back, or a hernia, so a palpable knot does not identify the cause by itself. Pain with coughing, a visible bulge, numbness, or pain into the thigh changes the assessment.

Temporarily avoid sprinting, wide lunges, forceful stretching, and movements that reproduce sharp pain. Keep comfortable walking and gentle hip motion if these do not increase symptoms. Ice may help after a recent strain, while warmth can feel soothing for muscle tightness. A physiotherapist may use [Manual Therapy](/treatments/manual-and-manipulative-therapy/manual-therapy/), [Myofascial Release](/treatments/manual-and-manipulative-therapy/myofascial-release/), or [Trigger Point Therapy](/treatments/manual-and-manipulative-therapy/trigger-point-therapy/) after examination. Persistent muscle-based symptoms may be discussed as [Myofascial Pain Syndrome](/conditions/myofascial-pain-syndrome/); [Dry Needling](/treatments/physiotherapy-and-rehabilitation/dry-needling/) is another clinician-selected option.

Seek prompt care for severe or sudden groin pain, inability to bear weight, a rapidly enlarging bruise, fever, testicular pain or swelling, or a groin bulge that is very painful or cannot be pushed back. Arrange an assessment when pain lasts beyond a short period, keeps returning with sport, or limits stairs, walking, or hip movement. New numbness or weakness also warrants medical review.

Ask whether the pain is from an adductor muscle, hip joint, tendon, abdominal wall, nerve, or hernia. Ask which exercises are safe, when strengthening can begin, and what return-to-sport signs should be met.
