Hi - you say "had" - does that mean the rash has gone away? And do the blood vessels look red, or blue? Just trying to clarify your symptoms... If you have an itchy rash, and perhaps you see red streaks (that look like blood vessels?), then it's certainly worth getting checked out. It could be an infection, which you'd certainly want to have looked at. Inflammatory breast cancer is an unsual type of breast cancer that can sometimes be misdiagnosed as an infection; it makes your breast itchy, or feel hot and swollen and painful. So, if you still have that rash - get it checked, OK? Good luck - PJH
