A hamstring strain is a partial tear of the small fibers of the muscles of the hamstring group. The hamstrings are the large group of muscles in the back of the thigh. They consist of three muscles that run from above the hip to below the knee joint.
A hamstring strain can be caused by:
A risk factor is something that increases your chance of getting an injury. Risk factors for a hamstring strain include:
Symptoms include:
The doctor will ask about your symptoms and medical history, your recent physical activity, and how the injury occurred. The doctor will also examine your thighs for:
Muscle strains are graded according to their severity:
For a severe hamstring strain, you may have an MRI scan to see if the tearing requires surgical repair. Professional and collegiate athletes sometimes have MRI scans to help predict the length of their recovery.
Treatment depends on the severity of the strain.
Treatment usually includes:
Do not do activities that cause pain, such as running, jumping, and weightlifting using the thigh muscles. If normal walking hurts, shorten your stride. Do not play sports until the pain is gone.
Apply ice or a cold pack to the hamstring 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.
Take aspirin, ibuprofen (Advil, Motrin), or acetaminophen (Tylenol) to help relieve pain. Ask your doctor if you have any questions about using these medications. If you still have tenderness in the hamstrings while taking these drugs, do not return to physical activity. First, check with your doctor before returning to activity.
Wear an elastic compression bandage (eg, Ace bandage) around your thigh to prevent additional swelling. Be careful not to wrap the bandage too tight.
Keep your leg higher than your heart as much as possible for the first 24 hours or so to minimize swelling. A couple of days of elevation might be recommended for severe strains.
Use heat only when you are returning to physical activity. Then use it before stretching or getting ready to play sports.
When the acute pain is gone, start gentle stretching as recommended by a healthcare professional. 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 hamstrings as recommended by a healthcare professional.
If you are diagnosed with a hamstring strain, follow your doctor's instructions .
