Around 6 months ago, my upper right eyelid was swollen suddenly. It caused discomfort but not too painful. I didn't see a doctor and took some antihistamine but it took a few weeks to get better and eventually disappeared after around a month. I do not know what caused it.
Yesterday, the area around my left eye was swollen when I got up in the morning. This time is more under the eye and on the upper left cheek. I took antihistamine but I don't see any improvement. My eyes are clear (no discharge) but the area around the left eye hurts a bit when I blink. I have a blister on my inside lower lip for a couple of days (not sure if it is related).
Is there anything I can do to cure this or if I can get anything from the pharmacy or is this something more serious that I have to see a doctor (if yes, will a general doctor help or a specialist eye doctor)?
