Wisdom teeth extraction complications?!

Wisdom teeth extraction complications?

PLEASE READ CAREFULLY

Its tuesday day 5 so I am finally starting to get over the pain. I still have numbness on the left side of my jaw and lip. The Dr. said it was from the swelling pressing on a nerve. He is not worried about it but wants to keep an eye on it. I am also having trouble opening my mouth. It feels like the right side of my jaw will not stretch properly. It is agony to try to chew anything and that is only when it is soft enough to squish it in between my teeth. I can fit a spoon or fork in my mouth but if it piled high anything on it falls off.
Questions refer particularly to the stiff jaw not so much the numbness although additional info on that is welcome.
Has anyone experienced anything like this?
What is causing it?
When will it go away?
Is there anything aside from heat I can do to help it along?
Are the two problems related(numbness and stiffness)?

Answer will not be chosen for best if you talk only about numbness and tell me to talk to dr. Been to dr am going again. I am alternating ice and heat, and am taking pain meds and antibiotic.

My daughter had these problems with her wisdom tooth extraction...she said heat helped, but she lost 15lbs. from only eating jello. She was told the same thing by the dentist, it probably took about 2 weeks for the pain to go and another week for the stiffness.
