hydrangea,
when i first started having rash issues, they told me it was actinic keratoses. Did the whole cryosurgery thing to remove it since AKs are pre-cancerous. Froze multiple spots on my face and arms . . . which did nothing except irritate my skin further. Instead of it taking 2 weeks for the cryo to heal, it took about 4 months for the scabbing to go away and, lo and behold, my skin problems were still there and not improved at all. It is very possible they will go ahead with surgery, even if you have a rash - especially if you are having it done as an outpatient at your dermies office.
Pelvic pain with cloudy urine? Some sort of urinary tract infection, maybe . . . I would have it checked out. Really, truly . . .
