Female experience please help! i don't know what to do!

I have no idea what it is.

Long story short. I developed a little red spot in my inner thigh since xmas. It's itchy. DR gave me antifungal cream. It is no use. It spreads to the labia. The Dermo dr gave me Travocort. She thought it was interiego: Ezecama + fungal. I applied for 4 weeks. It eases some itchy. But my labia is extremely red and so does the vulva. Later, my vaginal is extremely painful like pins and needles and burning sensation. I went to O&G, she said it was my skin problem in my inner thigh- Tinea, resulting in vaginal infection. Later, my urethra got infected as well.

Now I was on Antibotics and Antifungal (Duflucan for 6 weeks, once each week). Seems the pins and needles sensation went away mostly. I still applied Travocort but seems no use. The affected area turns into very red when wet /hot.

Should I do a fungal skin culture on those area? Or fungal test on vaginal discharge?
Could the fungus go inside?

There is no skin peel? I wonder if it's typical ringworm or mutated fungal/ringworm becoz of the use of steriod.

Any thoughts are welcome. thx Tweet
