I Have Been Having Pain In An Area Under My

I have been having pain in an area under my left breast. it radiates around to my back. Sometimes it last over a week. I don't have to be active when it decides to act. it is very painful and most times it is very hard to take a deep breathe.

I need help can't afford the doctor I have went to. I am afraid, had cancer before.
Thanks for your nonhelp. Can't people help others without charging?
