Diagnosis

How is EM diagnosed?

Erythromelalgia can be diagnosed through observation and interview of the patient. A doctor who has knowledge of erythromelalgia (or the symptoms of autonomic nervous system dysfunction), can make a diagnosis of EM by asking pertinent questions of the patient and observing the affected body parts. The doctor will be looking at "tell-tale" signs of EM, such as, hot feet, burning pain and/or redness occurring in warm or increased temperatures, after exercise or extended period of time on feet and worsening in the evening/night time hours.

Another critical element of the diagnosis of EM is how the person can attain relief from the pain and discomfort: through elevation and cooling of the involved extremity (hands, feet, toes, etc.) The patient must tell the doctor about their method of attaining relief and any other affect the symptoms have on their lifestyle.

Therefore, the patient should be prepared for these circumstances by bringing a copy of:
