They call me "Puffy"

I had a cavity filled last week Tuesday and my face has finally returned to it's original size. The dentist isn't sure why but after I had the cavity filled my face puffed up and became very painful. They first thought it was an abscess but they couldn't find one. Then they thought it was a hematoma but I didn't have the characteristic bruise. It took two dentists to decide that I either had a reaction to the anesthetic or I have a needle track infection. Either way I am once again a statistical outlier.
