hi...I am a healthy female, 54 yrs old...i woke up two mornings ago with a severe, sharp pain in the left, back, rib area of my back. The pain is so sharp and intense that I can t breath or talk. It feels like a cramp. This happens when I move my body a certain way. It is not constant. When it isn t sharp, intense pain it is just a dull ache in the same area. I have been under a tremendous amount of stress and am hoping its not related to that in some way....thank you for your time....Pamela
