I am 28 years old female. I am 4" 10 and my weight is 50 kg. My upper eyelid area usually get swollen. I am feeling that my right side upper eyelid area do not get back to normal as compared to left side eyelid area. There is slightly drooping of right side eyelids skin as compared to left eye. I got checked my eyes in hospital everything was normal. And they suggested me to check thyroid function. It was also normal. There is no pain also in my eyes. What could be the reason for it? Sometimes I feel that I am over thinking about it. Please give your advice what should I do about it?
