A muscle strain involves damage to the muscle due to strenuous activity. Individuals of all ages can place unwanted tension on the muscles while performing normal daily activities.
A severe cases of muscle strain can result to a muscle tear. The torn muscle can also impair the small blood vessels, resulting to localized bleeding and pain.
What are the possible causes and risk factors?
A muscle strain can develop to individuals of all ages. It can occur while performing daily activities or abrupt use of the muscle during activity.
Certain activities that increases the risk for ending up with a muscle strain include athletic activity in sports with abrupt acceleration or deceleration, rapid throwing and/or heaving lifting, sudden coughing or injury while engaging in irregular work.
It is likely for a muscle strain to occur on any muscle that moves the bones. The commonly strained muscles include the following:
- Lumbar muscles
- Hamstring muscles of the posterior thigh
- Abdominal muscles
- Quadriceps muscles of the thigh
- Calf muscles
- Upper back muscles including the rhomboid and trapezius
- Neck muscles
- Intercostal and oblique muscles of the chest
What are the indications of a muscle strain?
In most cases, an individual with a muscle strain experiences the following:
- Bruising, swelling or redness or even open wounds due to an injury
- Pain in the involved muscle while at rest
- Pain when a specific muscle or joint linked to that muscle is used
- Weakness of the muscle or tendon
- Difficulty or inability to use the affected muscle.
Eventually, the symptoms tend to vary depending on the muscle involved and the harshness of the injury.
