Strain

What are muscle strains?

Most muscle strains (pulled muscles) are caused by overstretching muscles. Strains may be minor or severe, such as a torn muscle or tendon.

Symptoms of a muscle strain can vary depending on how severe the strain is and may include:

  • Pain and tenderness that is worse with movement.
  • Swelling and bruising.
  • Normal or limited muscle movement.
  • A bulge or deformity at the site of a complete tear.

Recovery time for a muscle strain can vary depending on a person's age and health and the type and severity of the strain. While a minor strain often heals well with home treatment, a severe strain may require medical treatment. If a severe strain is not treated, a person may have long-term pain, limited movement, and deformity.

  • When to call

    Muscle strain: When to call

    Call your doctor now or seek immediate medical care if:

    • You have new severe pain.
    • Your injured limb is cool or pale or changes color.
    • You have tingling, weakness, or numbness in your injured limb.

  • Treatment

    How can you care for your muscle strain?

    • Rest the strained muscle. Do not put weight on it for a day or two. If your doctor advises you to, use crutches or a sling to rest a sore limb.
    • Put ice or a cold pack on the sore muscle for 10 to 20 minutes at a time to stop swelling. Put a thin cloth between the ice pack and your skin.
    • Prop up the sore arm or leg on a pillow when you ice it or anytime you sit or lie down during the next 3 days. Try to keep it above the level of your heart. This will help reduce swelling.
    • Take pain medicines exactly as directed.
      • If the doctor gave you a prescription medicine for pain, take it as prescribed.
      • If you are not taking a prescription pain medicine, ask your doctor if you can take an over-the-counter medicine.
    • Do not do anything that makes the pain worse. Return to exercise gradually as you feel better.
