Nerve Pain in Breast

I switched to Secret Platinum Clear Gel deodorant about two - three months ago. My armpits have been itching off and on since starting to use it. Most recently my left breast became painful and have had some nerve pain throughout the breast. I have had some nerve pain on the right breast as well. My injury massage therapist suggested I change my deodorant to an all natural brand without aluminum purchased at a health food store. The itching has gotten better since starting to use the new deodorant three days ago, but still having some nerve pain in my breast. Has anyone ever experienced anything like described?
