Itching with burning on urination often points to either a vaginal infection, a urinary tract infection, or both together, since the two areas sit close by.
Next Steps
A urine test and a vaginal examination will show which one you're dealing with, so please see a gynaecologist this week.
Health Tips
Keep the area clean and dry and avoid tight synthetic underwear until you're seen, and don't start any cream on your own.
