If you have any skin pigment changes?
There is a bronzing of the skin that occurs with hemochromatosis, that is often mistaken for melasma in women.
Hemochromatosis is a hidden disorder, that shows up only when it is in serious stages. Often it is not tested for. But it deposits iron in the tissues, and may cause PN.
There are special blood tests for it. Kaiser-Permente HMO is now screening all patients for it. This is a genetic disease and not that uncommon.

It is worth looking into.
