Diagnosed with Graves Disease 2 years ago and it has been stable since Sept 2015. Recently have been under high stress at work (past 3 months) and am feeling the symptoms of Graves coming back. Specifically, fatigue, insomnia, shortness of breath, difficulty concentrating, etc. Also have recently experienced pressure in left chest area and back of the neck pain. Had EKG test yesterday and have follow up with Specialist on July 11th. Family history of heart problems.
