I'm so sorry you are going through this.
Someone here recently had a similar issue in the same area, and I believe she found that a Steroid/Antibiotic cream worked better than just a steroid cream.
Maybe try Fucidin H, steroid WITH antibiotic cream.
Otherwise, plenty of sitz baths with salts. If you can get dead sea salt it works so well.
Also, if it were me, I would be tempted to mix a drop of oil of oregano with olive oil and applying a teeny teeny amount. O of O is a powerful antibacterial, anti-fungal, anti-viral and might sting a little bit, but it might be worth a try.
I hope you get some relief asap, and let us know how you make out.
