Hi! Three weeks ago i had a throat inflammation and then again a week ago. I don't have tonsils but it felt as a mild tonsillitis. I still have some sinus-mucus problem, but very mild. Under a lot of stress, few days ago I developed a rash around chest and neck and severe scalp itchiness. I scratched and hours later my face was bloated, like full of water. Could this be scarlet fever or an unrelated case of allergy? I'm 38.
