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 muscles will need time to heal. RICE is often the main part of treatment: Rest—Activities will need to be restricted at first. Normal activities will be reintroduced gradually. Ice—Ice therapy may help relieve swelling. Heat or cold may be advised throughout recovery if they provide benefits. Compression—Used for a limited time, compression bandages can provide gentle pressure to help move fluids out of the area. Elevation—Keeping the area elevated can help fluids drain out or prevent fluids from building up.
Prescription or over-the-counter medications may be advised to reduce pain and inflammation.
To help reduce your chance of getting a groin strain, take the following steps: Keep your adductor muscles strong to absorb the energy of sudden physical stress.Learn the proper technique for exercises and sports.Warm up your muscles slowly and stretch them properly.
