you cannot adequately or accurately determine a specific cause of vaginal itching or irritation over the internet but the most likely cause would be yeast. keep using your vaginal yeast medication including some topical anti-yeast cream on your itchy areas. if this does not help you may need to see your medical provider for a proper examination.
vaginal irritation:my only symptoms are itchy red some discomfort/dryness mostly itchy. no unusual discharge or smell. sex w/ bf abt 4 nights ago dry & its been uncomfortable red/sore. no bumps/ doesn't hurt to pee no frequent urination discharge or odor. it comes and goes through the day. mostly irritated when i'm working or doing a lot of activity. i go commando at the gym/ i have been itching it. took yeast infection medication & finished it last night. could it be something serious other then irritation from sweat from the gym touching myself down there too often checking it &irritation from the sex?
