The recovery time after a woman’s swollen lower body depends on the cause of the swelling and the degree of swelling. If a woman has swollen vaginal opening after intercourse, it may be a local edema phenomenon caused by the stimulation and friction of external force on the lower body and vagina. Generally, local cold compresses can be applied for 15 minutes each time, and the swelling will subside in about 1-2 hours after repeated many times. If there is swelling of the perineum or genitals with local itching or pain, abnormal discharge, etc., it may be a temporary swelling caused by inflammation or infection by pathogenic bacteria. When the cause of inflammation or pathogenic bacteria is eliminated, the swelling will gradually subside, but the exact time will be determined by the doctor’s specific treatment plan. If a woman has swelling of one labia minora with obvious pain, it may be caused by an abscess of the vestibular gland, which requires not only treatment of inflammation but also incision and drainage of the abscess. In daily life, attention should be paid to keeping the area clean and dry, and warm salt water can be used to wash the vulva to avoid breeding bacteria and secondary infections.
