Im sure everything is going to be fine i have the same thing too it's like underarm/left breast on the side i went and had a mammogram done and i got a clean bill of health they said it's fat that didnt distribute through my body correctly and it accumulated in that spot. I had the same thing last year and it went away i have had it now for a couple of months so keep your spirits hight and im sure everything will be fine. Believe me i was in the same situation as you so i know you will be ok.
