CRP (C-reactive protein) is a non-specific marker of inflammation. Typical symptoms associated with elevated CRP include fever, fatigue, muscle aches, joint pain, swelling, or redness—depending on the underlying cause. Importantly, CRP itself does not cause symptoms; it is a lab value that reflects inflammation. Elevated CRP can occur in infections, autoimmune diseases, tissue damage, or chronic conditions like obesity and metabolic syndrome. A consumer blood test (e.g., Fitness | LifestyleCheck) provides a snapshot but is not diagnostic. If you have persistent symptoms or abnormal results, consult a doctor for proper workup. The evidence is based on clinical practice; no specific studies were provided in the context. Caveat: a normal CRP does not rule out inflammation, and a mildly elevated level can be due to benign factors like exercise or minor infections.
