How Lyme Affects the Muscles

The Borrelia burgdorferi bacteria damages muscles through inflammation and immune system disruption. Here’s how it works:

How Lyme Bacteria Affect Muscles:

1. Invasion of Tissues:

• After entering the bloodstream through a tick bite, Borrelia burgdorferi can invade tissues, including muscles, joints, and nerves.

• The bacteria can hide in connective tissues like collagen, where they are less visible to the immune system.

2. Triggering Inflammation:

• The body’s immune system detects the bacteria and overreacts, releasing inflammatory chemicals (cytokines).

• This inflammation causes muscle pain, swelling, and tissue damage, leading to symptoms like soreness, stiffness, and weakness.

3. Immune System Confusion (Autoimmune Response):

• In some cases, the immune system mistakes healthy tissues for the bacteria because of molecular mimicry (when bacterial proteins resemble human tissue).

• This can cause the body to attack its own muscles, leading to ongoing inflammation and damage.

4. Toxin Release:

• While Lyme bacteria don’t produce classic toxins like some other bacteria, their presence disrupts cell functions, causing oxidative stress, tissue damage, and inflammation.

5. Nerve Involvement:

• The bacteria can also infect nerves (neuroborreliosis), disrupting the signals that control muscle movement and causing:

• Muscle twitching

• Weakness

• Spasms

Summary:

The bacteria causes indirect damage by:

• Triggering an inflammatory response

• Hiding in connective tissues, causing chronic inflammation

• Disrupting nerve signals that control muscles

• Possibly confusing the immune system into attacking muscle tissues.

This chain reaction leads to muscle pain, weakness, and spasms seen in Lyme disease.
