About once a month, sometimes more frequently, I get a swollen eyelid. It is always the same eye. It starts as like a bubble on my eyellid, then progressively gets larger and larger. I can usually tell when it is going to happen because it itches. As soon as I touch it, it gets extremely large. It looks like my lid is filled with air. The swelling usually lasts for about a day, and nothing I have tried will reduce the swelling. It has been happening for years, yet no one can tell me what causes it. Everyone keeps telling me it is an allergy, but I believe that isnt true. I have documented what I eat, where I have been, soap, detergeant, make up, etc. Nothing comes up the same. Sometimes I wake up with it. Please help. Can you tell me what might be causing this, and how I can prevent it from happening. The eye itself seems to be fine.
