I have a sun allergy(well to somthing in the sun). i thought it could be suncream ect but i changed to make and it didnt help. it got really bad whilst i was abroud last year and i went to a hosp out there and they said that it was possible it was the sun, and gave me sum cream to take down the rash and sum tabs to take and sum v high spf suncream. it got better but the rash came back in the sun on a trip 2NYC earlier this year, so on gettin back i went to my Gp who told me to always use high SPF cream all the time and not go out w/o it. It is summin u can grow into so its possible u have grown into it.
Ive never heard its related to the pill, but if ur worried y not see ur GP?
