I had unprotected sex on 11/01/2022 and after two days I started feeling pain in my lower region, Vagina in particular. Whenever I set, it hurts me a lot and I cannot sit normally I have to tilt to one side and then sit. The area inside the Vagina is quite itchy and it feels the urge to itch only whenever I sit suddenly ( without tilting). I tried scratching with little force so that the itching can go away but it didn't help. I'm peeing normally, it doesn't burn while peeing but during peeing I feel the itching inside the vagina and a little pain. Is it something serious? I really need a solution ASAP as I wasn't able to sleep last night just because of that itch. Help!!
