Ninety patients will be examined clinically to determine a diagnosis of cellulitis or fluctuance. The diagnosis will be confirmed by incision and drainage. Patients will receive either 3.6 ml 4% lidocaine with 1:100,000 epinephrine or 3.6 ml 4% lidocaine with 1:100,000 epinephrine buffered with 8.4% sodium bicarbonate.
