Late last night, my son had an allergy attack, presented eventually as a nose bleed that would NOT go away.
His face was severely puffed up and the lymph nodes in his throat were swollen, BUT his damn nose would NOT stop bleeding.
By the time {my wife, actually saved the evening, having a history of this sort of thing in her distant youth} it was finally stopped, my son had just but passed out with pain.
Fortunately, it was Dr. Martin Luther King day and there was no school. He slept most of the morning.
He seems fine now.
Hope you are OK as well.
