What is the treatment for addison's disease- is it cureable
If I think I have it, what kind of tests should I have?

Addison's disease: Symptoms - MayoClinic.com

Addison's Disease - Symptoms, Treatment and Prevention

These two sites give excellent info on Addison's symptoms and treatment.

Your doctor is the one to discuss what tests will be necessary to properly determine if you do in fact have this disease.

I am not aware if it is curable or not but it is treatable with the proper medication and management by your doctor.
