Vaginal swelling, itching, rashes, and brownish discharge around periods are often due to a local infection or irritation, sometimes mixed with old blood appearing as brown discharge. Keep the area clean and dry by washing gently with plain water, wearing loose cotton underwear to reduce moisture and friction, and avoiding scented products, tight clothing, or pads for too long, as they can worsen irritation. Continue your medicine as advised, change pads regularly to maintain hygiene, and allow some air exposure when possible to help with healing. Avoid scratching, as this can increase irritation. If the discharge becomes foul-smelling, symptoms worsen, or pain increases, consult a doctor to confirm the cause and guide proper treatment.
