Initial Assessment: History and Physical Exam
The first step is a comprehensive medical history and physical examination. Doctors look for key symptoms, like morning stiffness in arthritis or burning pain in neuropathy, to narrow down potential causes. Understanding the patient's pain characteristics and associated symptoms helps guide further testing and treatment decisions.
Using Lab Tests Wisely
Laboratory tests can confirm suspicions raised by the initial assessment. Tests like ESR and CRP indicate inflammation, while autoantibody tests can suggest specific autoimmune diseases. However, these tests aren't always definitive, and false positives can lead to unnecessary additional tests.

Imaging and Advanced Diagnostics
When the source of joint pain remains unclear, imaging studies like X-rays or MRIs can provide valuable insights. These tools help visualize joint damage or inflammation, while synovial fluid analysis can confirm infections or crystal-induced arthritis.
