Pain in breast area & Tieze question

Do any other women feel pain mostly on their chest in the breast area?

When I press on my chest, the majority of my pain is where my breast starts on the left side of my chest, is that the case for anybody else?

Also I’m thinking I may have tieze. The right side of my chest has a lump that’s just come up about 5cm under my collarbone. But I get hardly any pain there. It’s a rock hard lump on what feels like my rib bone. Does anyone else have this?
