Fr a few weeks now I've been suffering with a pain which can range from sharp to dull seemingly under my left breast. I can't determine whether it's coming from my breast itself, the ribs or inside the chest but sometimes the pain moves around the back (back of the rib cage, again on the left side) and down my left arm. I know that sounds bad but aside from heart problems, what else could this be?
Sometimes it feels like wind (I sometimes can't breathe in when the pain is there as it gets worse on breath intake) and other times it feels like injury/bruising type pain that isn't effected by my breathing.
Other symptoms I get it dizzy when standing, loss of appetite and feeling full as soon as I start eating.
I am under a lot of stress at the moment, could it just be stress related?
