Symptoms of Strains:-
The symptoms of a strain can vary in severity, depending on the extent of the damage. Common signs include:-
- Pain: Often sharp and immediate with acute strains, or a dull ache that worsens with movement for chronic strains.
- Tenderness: The injured area is painful to touch.
- Swelling: Accumulation of fluid around the injured muscle.
- Bruising or discoloration: Due to bleeding from torn blood vessels.
- Limited range of motion: Difficulty moving the affected limb or joint.
- Muscle spasms or cramping: Involuntary tightening of the muscle.
- Muscle weakness: Difficulty using the affected muscle for normal activities.
- A “pop” or “snap” sensation/sound: Heard or felt at the time of injury, indicating a more severe tear.
- A “gap” or “dent” in the muscle: Visible in cases of a complete tear.
Grades of Strains
Similar to sprains, strains are classified into three grades:-
- Grade 1 (Mild): The muscle or tendon is stretched or has microscopic tears. There is mild pain, tenderness, and slight stiffness, but strength and range of motion are generally maintained. Recovery is usually quick.
- Grade 2 (Moderate): A partial tear of the muscle or tendon. More significant pain, swelling, bruising, and noticeable weakness are present. Movement is painful and limited.
- Grade 3 (Severe): A complete tear or rupture of the muscle or tendon. This causes severe pain, significant swelling and bruising, and a complete loss of function in the affected muscle. A “pop” may be heard, and a visible gap may be present. This type of injury often requires medical intervention, possibly surgery.
