Hi , Welcome To HCM & Thanks For Asking Your Query Here Symptoms you mentioned are highly suggestive of Vulvovaginitis (swelling or infection of the vulva) which is most commonly caused by Yeast fungus , bacteria, viruses, or parasites , soaps, vaginal birth control, feminine sprays, & perfumes and Lack of cleanliness You should Keep your genital area clean and dry ,Avoid soap Just rinse with water to clean yourself , Soak in a lukewarm water ,Avoid using hygiene sprays, fragrances, or powders in the genital area , Use pads instead of tampons while you have an infection. Wear loose-fitting clothes and cotton underwear (instead of synthetic fabrics) ,Don t wear underwear at night when you sleep Along with these you can use over the counter anti bacterial and anti fungal cream if your symptoms do not improve within 3-5 days than i would strongly suggest you to see a Gynecologist to rule out any underlying medical condition because there are many less common conditions which may also cause it Including an STD , Contact Dermatitis ,eczema etc So it needs thorough medical check up and investigations to spot a confirm diagnosis I hope it help Thanks & Get well Soon
