The Difference Between a Strain and a Sprain

A strain is a slight stretching or complete rupture/tear of muscle fibers.  This injury usually occurs between the muscle belly and the tendon of the muscle.  This can occur within muscle fibers when the fibers become over stretched or when the muscle generates more forces than it can stand.  There are three degrees for muscles strains:

• First-degree: involves over stretching of some of the muscle fibers which can cause point tenderness in the involved area, mild swelling, and pain with muscle contraction.

• Second-degree: involves some of the muscle fibers actually tearing. Some of the symptoms include point tenderness to the involved muscle, swelling, bruising, and pain with muscle contraction.

• Third-degree: involves a complete rupture/tear to the muscle fibers and blood vessels. Symptoms for this include pain, loss of function, evident defect where the muscle ruptured, swelling, and bruising.
