Swollen and very sore to touch, neck and face after wisdom tooth extraction?

I got my left lower wisdom tooth extracted yesterday, my face started swelling and became painful as soon as i left th surgery. Its swollen that much i look deformed and and my neck and face r extremely sore to touch. Its also painful swallowing liquids r trying 2 open my mouth. Ive got antibiotics from the dentist but they dont seem 2 b helpin yet. Is this normal?
