<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been feeling ill lately and my ribs hurt. I also have a history of drug abuse. What could be causing this?  <response>: It sounds like you may be suffering from Glucocorticoid deficiency. This condition occurs when the adrenal glands dont produce enough of the hormone cortisol, which can cause symptoms like the ones you described. Lets get some tests to confirm the diagnosis.
