The patient feels hot when those around feel cold. One detrimental aspect of Graves' is Graves' ophthalmopathy. The eyes bulge because inflammation cells and inflammation goop fill the eye socket. Inflammation goop infilterates eye muscles, disturbing their co-ordinated movements resulting in double visison.
