I hurt my neck and back vacuuming a mattress. Within a few hours I hurt all over and was very nausuas and was freezing and sick all over like the flu. Was also so weak. During the night I must have sweat like crazy and my bed and pillow were very wet. Today my face is so swollen it hurts to touch it and it goes down under my jaw. I feel better as far as the aching goes, but my face feels like it will explode.
