It is possible to have axillary lymph nodes affected by having an axillary surgery because the surgery for armpit odor is mainly performed in the armpits, so it is possible for the axillary lymph nodes to be damaged during the surgery. Armpit deodorant surgery is mainly a surgical method of removing sweat glands in the armpit area to reduce sweat secretion and bacterial reproduction in order to treat armpit odor. It includes suction and scraping, small incision subcutaneous trimming and so on. There is a possibility that the lymph nodes in the armpit will be damaged during the operation, and at the same time, as the operation is performed in the armpit, it will lead to surgical incisions in the armpit, deterioration of the local blood supply, subcutaneous adhesions, hematoma and so on. Therefore, the chance of postoperative infection is greatly increased, which can lead to redness and swelling of the axillary lymph nodes. Therefore, after armpit odor surgery, it is often necessary to follow the doctor’s instructions to take amoxicillin, cefaclor and other antibiotics to prevent infection.
