 [ Symptoms ] is dry skin common during pregnancy  since i have been pregnant i have been really itchy mostly my arms legs back and belly and as i have gotten further along the itching has gotten worse i was told on my belly i have a pregnancy rash is what my dr called it but i have no explanation for the rest of the areas [ Disease ] it would be very very difficult to determine the nature of a skin lesion without seeing it first hand you may be describing a halo nevus but without examining you first hand this is just a blind guess
