Diagnosing Chronic Pain

Unfortunately, chronic pain can take a long time to diagnose because its symptoms are often similar to other chronic illnesses or disorders. However, there are some commonly used tests and procedures your doctor will use when diagnosing your chronic pain.

Classes of Chronic Pain

There are six classes of chronic pain, based on how pain is detected and interpreted. Each causes a specific type of pain, and must be treated in a specific way.
Types of Chronic Pain

Chronic pain can be caused by disease, injury or psychological disorder. While there are countless conditions that cause chronic pain, the most common types are back pain, headache pain and joint pain. Other common chronic pain conditions include cancer pain, pain syndromes and pain from depression.
Chronic Pain in Specialized Populations

Even the same chronic pain conditions can affect people differently based on their age, sex or background.
Unusual Types of Chronic Pain

Not all cases of chronic pain are limited to the back and joints. Sometimes, chronic pain has a more unusual cause.
