(Adductor Strain; Groin Pull; Pulled Groin; Pulled Groin Muscle; Strain, Adductor; Strain, Groin)
A groin strain is a partial tear of the small fibers of the adductor muscles. The adductors are a group of three muscles located on the inner side of the thigh. They start in the groin area and run down the inner thigh to attach to the inner side of the knee.
Muscles of the Groin
A groin strain can be caused by:
- Stretching the adductor muscles beyond the amount of tension that they can withstand
- Suddenly putting stress on the adductor muscles when they are not ready for the stress
- Using the adductor muscles too much on a certain day
- Getting direct blow to the adductor muscles
These factors increase your chance of developing a groin strain. Tell your doctor if you have any of these risk factors:
Participation in sports that require bursts of speed, such as:
- Long jump
- Tight groin muscles
- Cold weather
- Pain and tenderness in the groin area
- Stiffness in the groin area
- Weakness of the adductor muscles
- Bruising in the groin area (if blood vessels are broken)
- Popping or snapping sensation as the muscle tears (possibly)
The doctor will ask about your symptoms, medical history, physical activity, and the injury. Your thigh will be examined for:
- Tenderness and/or bruising directly over the adductor muscles
- Pain or weakness when contracting the adductor muscles, particularly against resistance
Muscle strains are graded according to their severity:
- Stretching with some microtearing of muscle fibers
- Recovery: 2 weeks
- Partial tearing of muscle fibers
- Recovery: 1-2 months
- Complete tearing (rupture) of muscle fibers
- Recovery: three months
For severe groin strains, you may have an MRI scan . If you're an athlete, your doctor may have this test done to help determine how long your recovery will be.
Treatment depends on how severe the strain is. It usually includes:
- Rest—Do not do activities that cause pain. If normal walking hurts, shorten your stride. Do not play sports until the pain is gone.
- Cold—Apply ice or a cold pack to the groin area for 15-20 minutes, four times a day, for several days after the injury. Wrap the ice or cold pack in a towel. Do not apply the ice directly to your skin.
- Pain relief medications—Ask your doctor which over-the-counter medication
Check with your doctor before returning to activity.
