Hi, 2 weeks ago I injured my back and neck, I went to see a physical therapist and she pressed hard on my spine (thoracic) that felt painful. A few hours later I started having pain in the thorax, then the following day a burning sentation in mi entire left breast and sternum, it is slowly getting better but I noticed a hard painful lump, any idea what it can be? can she have injured rib or sternum from pressing on my spine?
