Hi, I have never used this type of service. But my problem is this, I have some weired sensation on the left side of my breast (no breast pain at all). It is just at that height of my chest area, but more towards the back. It feels at times like burning and as if I have more flesh/ fat tissue around that area than on the other side. It is not all the time there. The left side is also my prefered sleeping side. I am also a big girl and somewhat top heavy.
