Do I have an genital ulcer?

ive been so scared these last few days. Basically, i had a very itchy vagina around last wednesday. i was very itchy and scratched it non stop which wasnt great. I applied some thrush cream and it burned terribly on the cuts. I saw a cut on the top of my urine hole but this has now developed into an ulcer looking type. I also am very sore in the bit between my urine hole and vagina between my lips. (sorry for not using the correct term!)

I searched online and it non stops speaks about STI which triggers a fear in all of us! Took a test and negative.

  1. are they ulcers?
  2. have i got them from scratching?
  3. how to treat them?
  4. how long till they go away?

Yeast infections can cause this. Especially from scratching. you can get ulcerations from the yeast left untreated. Can you get an antifungal pill?
