A groin strain is a partial or complete tear of the small fibers of the adductor muscles. The adductors are a group of 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.
Groin strain is a common sports-related injury. Treatment depends on the severity of the strain.

Talk with your doctor about the best treatment plan for you. Recovery time ranges depending on the grade of your injury. Treatment steps may include:
Your muscle will need time to heal. Avoid activities that place extra stress on these muscles:
Apply an ice or a cold pack to the area for 15-20 minutes, four times a day, for several days after the injury. Do not apply the ice directly to your skin. Wrap the ice or cold pack in a towel.
To manage pain, your doctor may recommend:
Use heat only when you are returning to physical activity. Heat may then be used before stretching or getting ready to play sports to help loosen the muscle.
When the acute pain is gone, start gentle stretching as recommended. Stay within pain limits. Hold each stretch for about 10 seconds and repeat six times. Stretch several times a day.
Begin strengthening exercises for your muscles as recommended.
If you are diagnosed with a groin strain, follow your doctor's instructions .
