11 year old son in the past two weeks have had swelling in the face and eyes at night well into the morning. Doctor ran blood test and found nothing, just a slight raise in blood protien indicating swelling, yet it was not high enough for alarm, even CT on sinuses..they were clear. I need a answer from someone because he is very uncomfortable, sleep is occassionally interupted however he is sleeping now due to fatigue. Oh and blood pressure is good also according to doctor. He is 100lb, 4"5in
