Lump after tooth extraction

I had an infection in my lower back tooth. The dentist treated it with antibiotics then took out the tooth 2 weeks later.
I then had more swelling about a week after and a lump in the side of my mouth.
The dentist gave more antibiotics after an x-ray but 2 weeks later the lump has got bigger.
The dentist is now confused to what it could be and has sent me to the hospital.
I am waiting to hear, but am very worried.
The lump is proberly due to the extraction as it was not there before.
