I had a three dall decompression on each eye and the pain was minimal. There is a nerve that goes under the floor of the eye socket and the trama of the eye socket being removed kind of shuts the nerve down. The feeling comes back over a period of months. By time the feeling comes back you are healed and there is no pain.
I have had 12 eye surgeries and must say the decopmression was the least painful of all of them. E-mail me if you want to talk about this. Or give me a call at 407-254-9719 and if I am not home leave a message in the National Graves Disease Foundation box on my answering maching. I will call back collect.
