My normal and healthy 9y/o son has an approx 1.0 cm swollen area on his left upper lip. Does not appear fluid filled, no drainage, no discoloration, no injury that he can recall, tender to touch, no other complaints. The area just looks odd. I can t recall seeing anything looking this way before. I was in nursing for 30+ years before I went on disability due to an ICH. He does keep fooling around with the area. Maybe he is making it look worse than it really is.
