Patients experience exacerbations, leading them to present to the emergency department (ED) for incision and drainage. Direct injection of local anesthetic into these lesions is extremely painful and seldom provides adequate anesthesia. A modified method of the PECS II block can provide anesthesia to the skin of the axilla, making management of HS much less painful for the patient. We performed a bilateral modified PECS II block on a patient requiring incision and drainage of HS lesions in both axillae. She subsequently required no local anesthetic for the procedure.</p></div><div><h3>Discussion</h3><p>The second injection of the traditional PECS II block involves the deposition of anesthetic in the fascial plane between the pectoralis minor muscle and the serratus anterior muscles.
