• A sprain is when a ligament  (the tissue connecting bones at a joint) gets stretched or torn.
• A strain is when a muscle or tendon  (the tissue connecting muscle to bone) gets stretched or torn.
• Common examples include low back strain, when you “tweak” the paraspinal muscles (surrounding the spine), and they hurt due to spasm. Also, an ankle sprain involves stretching/damaging the ligaments (tough tissues connecting bones together) when the joint is overstretched/rolled, and/or twisted against force.

Common Symptoms

• Pain in the injured area
• Swelling or bruising
• Stiffness or difficulty moving the joint or muscle
• Muscle spasms (for strains)
• Weakness or instability (for sprains)

Key Points

• Mild sprains and strains often improve with rest, ice, compression, and elevation (RICE).
• Severe injuries may need medical evaluation, physical therapy, or even a brace.
• Avoid using the injured area too soon to prevent further damage.
