Can a swollen eyelid from dust mite allergy result in droopy eyelids? (photo)

So, a few months ago I had a dust mite allergy. I would wake up and find bumps on my arms, neck and legs and they would be pretty itchy. A few days later, I woke up and my right eye was swollen. a symptom of dust mite allergy is swollen eyes. I could BARELY open my eye. I put ice on it for ~20 min, then it healed. A month later, my left eye became swollen. I put ice on it too, and most of it was gone. Now my left eye has a droopy eyelid. Do you think the swelling in my left eye damaged a nerve?
