What is the Difference Between a Sprain and a Strain?
Sprains affect ligaments while strains affect muscles or tendons. A sprain occurs when ligaments (tissues connecting bones) are stretched or torn, commonly happening in ankles, knees, or wrists. Strains involve overstretched or torn muscles or tendons (tissues connecting muscles to bones), frequently affecting the back, hamstring, or calf muscles. Sprains typically cause joint instability and bruising, while strains often produce muscle spasms and weakness. Both injuries share similar symptoms including pain, swelling, and limited range of motion. Grade 1 injuries involve mild stretching, Grade 2 includes partial tears, and Grade 3 represents complete tears requiring 6-12 weeks recovery time.
