Swollen Temples and graves disease

Hello,

I had hyperthyroid a couple of years back and been treated with radio active iodine medication in september 2010. I even had swollen eyes and looking at my eyes the doctor said I have graves disease.My roommates have noticed and informed me that due to bulged eyes when I am asleep I keep my eyes open. Sometimes while I am sleeping  I noticed my eyes water a lot and in the middle of sleep I wake up due to burning and rush to restroom real quick to wash them. The opthalmologists have suggested that I need to go through a surgery to reduce the bulging of eyes and I am scared of it. They have recommended me to use the eye drops like artificial tears during day and refresh pm ointment for the night and I am using them. Is there a way that I can reduce the bulging eyes and get my eyes normal without surgery??



Also, Since november 2010 my thyroid conditions have changed and I now have hypothyroid. Ever since the transformation of thyroid levels I have gained almost like 20 pounds of weight with in a month's time. And since then if the weather is cold or if I get a bit excited or if I eat anything hard my temples used to swell on both sides. But initially they never stayed longer than few minutes. Now I have been noticing that my temples swell quite frequently and staying for days and its causing me head pains frequently. I am not sure if this is because of graves disease or my thyroid. But I want to get rid of this. I dont have any issue with my vision or anything. So please suggest.

Thanks a bunch
