Hi,
I am 25 years old. My left eye looked a little bigger than the right one for a long time now.But, this was not by birth. Recently, (say from 1 year) the difference became more evident and now there is a slight pain around the left eye socket area. It becomes red as well. I also experienced twitching of left eye lid for a while(say 1 month), which stopped now. The left eye looks a little protruded out and little upwards than the right eye. I know that nothing can be told precisely without looking at me, but, any suggestions on what could be the reason?

Thanks,
-Kerry
