I woke this morning, and saw my face got swollen. Especially the my right eyelid area and also my right cheek area. Only a little area of my left side got swollen too. Why is this happening? Am I allergy to something? But, I ate what I usually eat. I am 19-year old, 5'4", 58.6kg. My medical history, I have a serious gastric problem and there was a few times when I checked my urine, there was albumin in my urine, but nothing happened then.
