I have a 12 year old boy who got a serious sunburn while skiing yesterday. He put lotion on his face to cool it off this morning and it got so swollen his eyes were barely open. We gave him 2 benadryl pills and he took a nap. Its been 4 hours and its still swollen and now has orange pus oozing from the lower half. Theres also a small spot on his upper lip that is scabbed. Is this sun poisoning and do we need to find an ER? We re in Colorado but live in Texas so no local doctor for us to ask. Thanks!
