- May cause tenderness and induration
- Exquisite tenderness on auricle manipulation
- Spontaneous rupture of Furuncle relieves pain- Purulent drainage may be seen
 
IV. Differential Diagnosis
V. Course
- Most Furuncles resolve spontaneously
- Incision and Drainage is rarely needed
VI. Management
- Warm compresses
- Incise and drain abscess if needed
- 
                          Antibiotics if needed- Indications- Cellulitis surrounding Furuncle
