Koke,
Yup, my eyes puffed up overnight, too. To me it looked and felt like I’d been stung by a bee
right between my eyes. The lids were very puffy. My docs (who I no longer see) said I must be
having an allergic reaction. Of course, it didn’t go away, and then the other eye symptoms showed
up–redness, feeling like rocks were in my eyes, sensitivity to light, etc. Good luck to you.
Find a good opthalmologist who understands Graves’ Disease.
