I don't know about the eye pain but dizziness and pain all over could be from anorexia. I would suggest going and talking to your doctor. Also people who are anorexic usually have other problems that are mental. Have you considered going and seeing a therapist, it might help.
Good luck. I hope every thing works out ok.
How do you know that Anorexia causes pain all over the body? I mean i'm sure it does, but this is aout my brother. He is 15 years old and he has been struggling with this eating disorder for a few months now, probably 6 or so. I also have struggled with this disorder myself, but I'm over it now. I just dont' know what to do about him, because he has like, no muscle mass left on him! He says he is experiencing aches and pains all over, and he is blind in hsi left eye, and has had surgery to move the muscle so that his eye looks the right way, because it crossed inward before. But I have heard this happens to other people as well. It is dizziness/vision blacking out, and last time the searing pain brought him to his knees. And he said last time that the pain was in his right eye. i'm just worried about him, and I would like facts if possible. Thanks :)
