Notes on Immune Disorders

Overview: The immune system is crucial for maintaining health, combating disease, and guiding treatment.

Symptoms of immune dysfunction can vary significantly based on the specific type of immune disorder.
Symptoms can range from mild to severe, and many overlap with other medical conditions.
This overlap complicates the diagnosis of immune disorders.

Low-Grade Fever: Recurring fever points to underlying immune activity.
Joint and Muscle Pain: Commonly reported in individuals with immune disorders.
