Itching, burning while urinating and thick white, curd-like discharge together usually point to a fungal infection of the vagina, which is common and treatable. The burning with urination can also mean a mild urinary infection sitting alongside it, so both may need checking.
Next Steps
A vaginal swab and a urine routine test will confirm which infection, or both, you have. Keep the area dry, wear loose cotton underwear, and avoid scented soaps or wipes until you're seen.
Health Tips
See a gynaecologist soon if the itching or discharge doesn't settle in a few days, or if you develop fever or pelvic pain.
