I was in Fiji in late August and used sunscreen religiously and didn't burn. I was there for a week.
On my arm, on the side is where it formed. Back in my high school days, I also put a cigar out in this same spot to unify with some friends after drinking.
Anyways, two sores right next to each other, pretty small, spots opened up and I'm afraid this could be skin cancer? It scabbed over but still pinkish in color and I just picked the skin off and it bleeds a bit.
I have some pictures of when it first formed and now but don't think I can add them on this thread.
