Have you told your nurse or doc about this? Could be sign of UTI 🥺 That's how I felt before this, itchy vulva, yellow discharge, back pain, headache, my vulva & stomach around my vulva also a bit sharp pain, lastly I suddenly vomit non-stop. Then I get warded for a week. Already discharged last week and still recovering ❤️🩹. Go get checked sis 🥺
