Anyone else randomly got a discomfort in their vagina?

Yesterday randomly my vagina was uncomfortably itchy and it still itches a lot but only if I wipe or touch and I itches it so much last night it kinda hurts not really hurt but uncomfortable to scratch. It’s more like the opening of my vagina. Came out of no were literally. Haven’t had sex since last week and I’ve been drinking water🤦🏾‍♀️ I might sound stupid but I don’t want to freak out. I washed my hair last night before it started so idk if it’s the shampoo maybe idk never had this happen randomly
