Why Sprains Trigger Excessive Inflammation

Inflammation: Your Body’s First Healing Stage

Even a mild sprain causes tiny fibres in the ligament or joint capsule to stretch or tear. Your body responds immediately by sending blood, nutrients, and immune cells to the area to initiate repair—a process central to effective treatment for sprains.

Inflammation:

– clears out damaged tissue
– increases circulation
– activates fibroblasts
– prepares the joint for healing

1. The Body Is Hardwired to Overreact

In early human history, a sprain came with:
– dirt and bacteria
– structural damage
– difficulty resting the joint

To protect you, the immune system evolved to overcompensate, sending more inflammation than technically needed.

This survival mechanism remains today, even though our environment has changed.

2. Nerves Amplify the Swelling

When tissue is injured, the nerves in and around the joint release inflammatory chemicals such as:
– Substance P
– CGRP
– Neurokinin A

These chemicals increase blood flow and make blood vessels leakier, drawing more fluid into the injury.

This nerve-driven process — neurogenic inflammation — can create a large swelling response even when the sprain is mild.

3. Your Immune System May Be “Primed”

If you’ve recently experienced:
– allergies
– asthma
– sinus inflammation
– infection
– high stress
– previous joint injuries

… your immune cells become hypersensitive.

This means they respond to even a small sprain with a large inflammatory wave.

4. Poor Lymphatic Drainage Traps Fluid

Swelling increases when fluid cannot drain away from the joint effectively.

This happens when:
– nearby muscles tighten
– the limb is kept still for too long
– lymphatic vessels are compressed

When drainage slows, fluid becomes trapped, and swelling can look much larger than the actual tissue damage.

Gentle, safe movement often reduces swelling faster than total rest.

5. Your Baseline Inflammation Matters

Some people naturally have a higher baseline level of inflammation. Common factors include:
– low omega-3 intake
– diets high in seed oils and processed foods
– poor sleep
– chronic stress
– respiratory or sinus inflammation
– hormonal changes

When baseline inflammation is already elevated, even a mild sprain can create an excessive swelling response.

6. Is All This Inflammation Bad?

Not always. Inflammation is a crucial part of the healing process.

The goal is not to eliminate inflammation completely, but to prevent it from becoming excessive, painful, or prolonged.

Supporting the body during this phase facilitates healing of injuries.

How Farrelly Chiropractic Helps Reduce Excessive Inflammation

At Farrelly Chiropractic, we use safe, gentle, and evidence-based methods to help your body transition from excessive inflammation into proper healing.
Every strategy is designed to reduce unnecessary swelling while supporting tissue repair.

What You Should Do After a Sprain (PEACE & LOVE)

The PEACE & LOVE framework was introduced in the British Journal of Sports Medicine and reflects modern, evidence-based management of sprains.
