What Is Inflammation?
Inflammation is the body's response to injury, irritation, or infection. It sends blood, fluid, and immune cells to an affected area. This response may cause warmth, swelling, redness, tenderness, or reduced movement. In sports injuries, inflammation can develop around strained muscles, sprained joints, or irritated tendons as the body begins repair.

Key Takeaways About Inflammation
- Inflammation is a response, not the injury itself.
- Swelling and tenderness may limit normal movement.
- Inflammation isn't the same as infection.
How Inflammation Works

Inflammation begins when damaged tissue sends signals for help. Blood vessels change near the affected area, and immune cells move into the tissue. Fluid can collect there, which may create swelling and pressure.

In sports injury care, a clinician checks how inflammation affects movement and function. The exam may include looking for swelling, feeling tender areas, and comparing joint motion with the other side. A strained muscle may hurt during contraction, while an irritated joint may feel stiff during movement.
How Inflammation Is Used in Sports Injury Treatment
Inflammation helps describe the body's response and guides the exam. The findings may be considered along with the injury's cause, pain pattern, strength, and range of motion.

From the Arrowhead Clinic - Lithia Springs team
When we assess inflammation, we look at swelling, tenderness, heat, and changes in movement. We also consider how the sports injury happened and which activities increase symptoms. Our team uses these findings to guide the physical exam and track functional changes during care.
Inflammation in Practice: A Real-World Example
A runner may develop inflammation around a strained calf after a sudden increase in training. The calf may feel tender and tight, and walking or pushing off can become uncomfortable.
