I Got My 2 Bottom Wisdom Teeth On Thursday, March

I got my 2 bottom wisdom teeth on Thursday, March 17th. When he did the extraction he was being rushed by another dentist & He closed the right side very quickly and didn't close it correctly because when I came home and the bleeding stopped I can feel how lose it was. The next day it came out. I felt a hard lump on the right side of face on my jawline and it is only getting bigger. The pain is very strong and im taking iburopfen 800 and it's not helping. The left side of my face is perfectly fine now( mind you, that side was more difficult to get the tooth out because it wasn't even grown in it ) the right side the tooth was already showing. I knew something was wrong because if anything the pain should have been more on my left side. The right side is very swollen and hurts a lot, especially if I touch the lump. It is now Sunday March 13, 2015 and There is a purple and yellow bruise & the pain is increasing. What can it be ?
