Diagnosis
Diagnosis involves interviewing the patient and performing physical exams. When attempting to establish the cause of the arthralgia, the emphasis is on the interview. The patient is asked questions intended to narrow the number of potential causes. Given the varied nature of these possible causes, some questions may seem irrelevant. For example, the patient may be asked about dry mouth, light sensitivity, rashes or a history of seizures. Answering yes or no to any of these questions limits the number of possible causes and guides the physician toward the appropriate exams and lab tests.
Treatment
Treatment depends on a specific underlying cause. The underlying cause will be treated first and foremost. The treatments may include joint replacement surgery for severely damaged joints, immunosuppressants for immune system dysfunction, antibiotics when an infection is the cause, and discontinuing medication when an allergic reaction is the cause. When treating the primary cause, pain management may still play a role in treatment.
