Have you ever thought that maybe you are allergic to cotton? I would do an allergy test seriously! then I would go to another gyno because something isn't rite sista...just not right! i'm sooooooooo sorry! Then I would use vaseline ALL the time! I would also bath in lavendar and oatmeal as much as possible. Sounds like eczema accept I don't know if you can have that down there.
