Abscesses on the back are generally larger because the back is an invisible part of the body, so usually small ailments are not easily detected. In ancient times an abscess on the back could lead to a life-threatening condition, commonly known as a hitching back, and people were cautious when an abscess on the back appeared. When an abscess appears on the back, it is necessary to go to surgery for surgical excision, which must be done completely to cut the abscess to the normal subcutaneous tissues, using a cross-shaped incision if necessary, to drain the pus completely. After cleaning with hydrogen peroxide and iodine, the gauze must be filled with gauze, and the gauze must fill the abscess cavity completely in order to provide adequate drainage. Then, oral antibiotics or intravenous antibiotics should be administered to combat the infection. Depending on the exudation of the wound, the medication may be changed once a day at the beginning and once every 2-3 days later.
