Hi,
Welcome to the forum. I am really glad to help you out. Take some precautionary measures like avoid wearing tight fitting clothing like jeans and pantyhose and underwear made from synthetic fibres.
Remove wet or damp bathing suits immediately after swimming, avoid douching, perfumed soaps, bubble baths and toiletries, change underwear daily, wash underwear in hot water (to destroy fungi) and double rinse (to remove any irritating detergent) and take adequate nutrition and sleep.
Also use some antifungal pessaries like clotrimazole, miconazole or nystatin after consulting your doctor. If still the symptoms persist then oral antifungals may be needed. Please consult a gynecologist in that case. I sincerely hope that helps. Take care.
