Hi everyone I'm a regular 19 year old. Yesterday I noticed a cluster of purple spots on my breast with tenderness. My nipples have also darkened  to brown in colour. It has made me worry, and I am thinking of calling the doctors but I don't want them to think I'm overreacting. I've been having slight pains in my upper chest and armpit and I don't know if they relate or not, any help will be appreciated thanks x
