Hamstring strains are classified as Grade 1, 2, or 3.
Grade 1 hamstring strain:
- Minor tear within the muscle
- Tightness in the back of the thigh
- Minimal discomfort while walking
- Possible swelling
Grade 2 hamstring strain:
- Partial tear in the muscle
- Possible limp when walking
- Pressure increases pain
- Flexing knee against resistance causes pain
- Sudden twinges of pain during activity
- Range of motion may be impaired
Grade 3 hamstring strain or tear:
- Complete rupture of the hamstring muscle Impaired mobility; may need crutches initially
- Severe pain; particularly when trying to flex knee
- Swelling
Initial treatment of all hamstring strains is:
-
Rest your hamstring; avoid any stress on it through sports or activity. Use crutches if necessary for a severe strain.
- Apply ice to the hamstring over a thin layer of cloth for 20 minutes, 2-3 times a day for the first 48 hours following injury.
- Use a wrap such as an ACE bandage or compression type device to decrease swelling and provide support as the muscle heals.
-
Elevate the affected extremity above the level of the heart with pillows for the first 48 hours when at rest.
Other effective methods of treatment include:
- Non-steroidal, anti-inflammatory medications such as Advil or Aleve can decrease pain and swelling.
- Begin a stretching program as soon as the pain/swelling decrease.
- Start a strengthening program to rebuild the strength of the injured hamstring and prevent further recurrence.
- Possible referral to physical therapy.
Your physician will monitor your progress and evaluate when it is appropriate for you to return to full activity. Prevention of hamstring injuries: It is easier to prevent hamstring injuries than to recover from them. Stretching before and after an activity is the greatest way to prevent a hamstring strain or tear.
