Immune-Related Pain
Autoimmune.

Autoimmune disease — definition, symptoms, types, tests, and its connection to pain — and why it must be distinguished from ordinary musculoskeletal pain.

§ 01Definition

What Is Autoimmune Disease?

It is a condition in which the immune system, for unknown reasons, attacks the body's own healthy tissues and organs.

It occurs when the immune system, which should be attacking outside threats such as viruses, bacteria, and certain drugs, malfunctions instead — a condition properly called "autoimmune disease," and much like an 'internal rebellion' in which allies are mistaken for enemies and attacked.

Tests to Diagnose Autoimmune Disease

Autoimmune conditions are often caused by autoantibodies, so confirming their presence is an essential step.

Blood autoantibody test
EX-01Blood · Antibody

Blood TestAutoantibody Test

Checks the blood for antibodies that attack the body's own tissue, such as ANA for lupus or RF for rheumatoid arthritis

Physical examination — history-taking and palpation
EX-02Physical Exam

Physical ExaminationHistory & Palpation

The doctor examines joint swelling, skin rash patterns, and muscle weakness through history-taking and physical examination

Specialized tests — imaging and tissue biopsy
EX-03Imaging·Biopsy

Specialized TestsImaging & Tissue

X-ray, ultrasound, or MRI imaging for a definitive diagnosis, with a skin or kidney biopsy if needed

§ 05Pain Connection

The Link Between Autoimmune Disease and Pain

One of the biggest features is that the symptoms include patterns typical of musculoskeletal disorders, such as pain and numbness.

Important

If you've had repeated physical therapy for what seemed like ordinary muscle pain or arthritis but it hasn't helped, there's a good chance the underlying cause is an immune system problem, not simple pain, and in that case it's worth checking for an autoimmune condition.
