Anna,
at the top of the page you will see a green thing that looks like a thyroid click on that and go to the links and look at the eye stuff all the symptoms you said are part of it. You can get the eye probelm and never develop graves, you can get it and then develop graves later or you can get graves and later develop the ey problems I belivev that only 20% get the eye problems.
RAI can make it worse but steroids will help.
Hope this helps
