Strains


Definition
A strain is when a muscle becomes overstretched and tears. This painful injury, also called a "pulled muscle," can be caused by an accident, improper use of a muscle, or overuse of a muscle.

Alternative Names
Pulled muscle

Causes
• Excessive physical activity or effort
• Improperly warming up before a physical activity
• Poor flexibility

Symptoms
• Pain and difficulty moving the injured muscle
• Discolored and bruised skin
• Swelling

First Aid
• Apply ice immediately to reduce swelling. Wrap the ice in cloth -- avoid using ice directly on the skin. Apply ice for 10 to 15 minutes every 1 hour for the first day. Then, every 3 to 4 hours.

• Use ice for the first 3 days. After that, either heat or ice may be helpful.

• Rest the pulled muscle for at least a day. If possible, keep the pulled muscle elevated above the level of the heart.

• Avoid using a strained muscle while it is still painful. When the pain subsides, start activity slowly and in moderation.

When to Contact a Medical Professional
• You are unable to move the muscle.
• The injury is bleeding.
Call your doctor if the pain does not go away after several weeks.

Prevention
• Warm-up properly before exercise and sports.
• Keep your muscles strong and flexible.
