Hi,
Definitely, the wound on your labia may be due to irritation by the tight lingerie besides so many other reasons. Cuts in the labial region may be many a times due to sexual intercourse or foreplay etc. Usually, many of the labial wound heal of their own with just simple care like avoiding the irritation to the affected area by avoiding sexual intercourse, till the healing of wound.
Wearing cotton underwear and loose bottom until the complete healing of wound. Washing the area with warm water once or twice a day. Avoiding perfumed or harsh soaps, as it can disturb the PH of vagina and affecting the healing in a negative way. Making sure that the area is dry before getting dressed again. During the healing process, it may be helpful, to wear pads for first several days to avoid irritation to wound and to soak any blood or discharge, from the wound.
You, may also use
topical medication like
bacitracin or a barrier ointment like Aquaphor to help soothe the area and aid in healing faster. If the pain is there, then OTC analgesics like
Tylenol or
Ibuprofen may be effective. However, if the healing is not there or the symptoms of pain and irritation become more, then you are advised to see your doctor and treated accordingly. Never use
local antibiotic ointment without consulting your doctor.
Take care. Hope I have answered your question. Let me know if I can assist you further.
