i had a mammogram done on jan 20,2012 and 4 days later i started getting little bumps on my chest that itched. it got progressively worse with my neck and chest getting inflamed and itchy but it burnt when i scratched.by the 27th my bra irri.,tated the area. i took a few baths in baking soda and it seemed to help it some.it is getting better now but my chest,neck and even my hands itch. is there a connection or am i nuts
