Eczema? Cancer?

idkwhatmyusershouldbe

So both of my nipples have been dry and very itchy. Especially when I get in the water?? Anyway, idk if I scratched too hard or this just appeared but I want to make sure it’s not anything serious. No lumps that I can feel, just severe itching and now this rash. I went zip lining yesterday so my arm pain if from that. Thanks girls, I’m just trying to save myself some stress.
