I Am A 51 Year Old Woman. I Am Having

I am a 51 year old woman. I am having alot of pain in my back. It is located on my left side between my ribs and hip bone. I work 50 hours a week and put up with lots of pain just being on my feet so much. So pain is nothing new to me but this is getting bad. If I push on the area it seems to relieve some of the pain. At this moment I am sitting with a heating pad on the area.
