Pain between ribs 4 and 5 just on the left of the sternum?

If your pain occurs especially when you breathe in and deeply, or when you press the area it hurts (like a pressure pain on the inside of your ribs) it may be a condition I was experiencing a few years ago- it has a long name which I don't remember, sorry. However it seems to occurs in women and is maybe to be related to what helps make us girls- breasts and the tension it causes on the chest.
