Hi mimumonschein
You might find this interesting reading as it identifies a link between vulval itching etc. and a high level of iron in the blood. Once you get this under control you may well find that the vaginal symptoms disappear
http://ir.uiowa.edu/cgi/viewcontent.cgi?article=1253&context=pogIt specifically says this
"identified 3 case reports with
generalized pruritus as the major
symptom prior to diagnosis of
hematochromatosis on a Pub Med
search.2-4 To our knowledge this is the
only report where localized vulvar
pruritus has been the presenting
complaint prior to the evaluation and
diagnosis of hemochromatosis. Rather,
we were anticipating iron deficiency
anemia as a possible systemic etiology
for her persistent pruritus.1 As noted
with the prior case reports, the temporal
improvement in symptoms after near
normalization of her serum iron and
ferritin levels suggest that the pruritus
was primarily due to the underlying
hematochromatosis.3,4 Thus, these
cases demonstrate how extremes of
serum iron levels may correspond with
vulvar itching and irritation"
