Hi, I Was Stung By A Bee Yesterday. Over That

Hi, I was stung by a bee yesterday. Over that past 24 hours it has swollen completely around my leg. It’s really hot and huge. I have also had fever and body aching. I’ve been icing it, putting cream on it and took allergy meds but it has continued to get worse. My doctor office is closed until morning and I’m trying to prevent from going to the ER.
