Swollen face after wisdom teeth removal ?

I got my lower two wisdom teeth removed 2 days ago and ever since I ve had a huge swollen face! I look like a lego man they re big puffy and hurt to the touch my actual teeth don t hurt it s just my cheeks and they re even starting to get bruised and purple how do I get rid of the swelling ? How long until y facade goes back to normal I can t miss anymore days of work and school :(
