Hi, I Had Six Teeth Pulled Four Days Ago, Every

Hi, I had six teeth pulled four days ago, every thing was fine till 230am lastnight when I had a sudden and extreme bout of freezing cold shakes. I turned up the heater to combat the shakes and when I finaly stopped being cold I started sweating excessively, so I turned off the heater and while my tummy still ached and I still had some gas and the craps, it was okay for the most part. Now all day long ive been fighting off the cold shakes, and the super hot sweats, drinking water and gatoraide like its going out of style. im wondering if this could be a sign of an infection in my mouth.
