What should I do? I m having sharp, stabbing pains on my left side, underneath my rib cage, below my breast. The pain seems to go through to my back and then up my spine. At the same time, every hour or so I get a pain in the center of my chest, it almost makes me feel weak. The pain in my left side is becoming unbearable. I m not sure if this is something I should worry about or just deal with. The pains started this morning and haven t stopped. I m female. 24yrs old.
