Why am I feeling really poorly eyes, legs, arms, neck, head, back and stomach hurting what is it I have?

See a doctor. It could be viral or something else. I advise you to see a doctor for detail evaluation and assessment. It's hard to advice without physical exam.
Viral illness? With your general malaise, achiness, stomach upset, irritation in eyes, it's possible you're affected by a virus. Because of your diabetes, i recommend that you call your md to discuss your symptoms so that an action plan can be discussed. Also check your blood sugar so as to know whether or not this is contributing to your symptoms.
