EXTREME ITCHING!!!!!

Emily • Nursing student 💉 💊
Hi guys, 
So I am having some problems. My eternal vulva itches to high heavens. I have itched so much in the last 24 hours it's unreal. I've had this before and I treated it as a yeast infection but it's definitely not as if never seems to go away. It's definitely not an STD either. I need help or thoughts on how I could treat this because it's becoming unbearable. 
I showed daily, sometimes even 2x a day. I just need some help. 
Thank in advance!!
