Hi, I have a pain above my ribs, below my breasts on both sides. It hurts to breathe. If I touch the rib under both breasts, it's painful. I have never experienced this before. I am using a muscle relaxer due to a back issue and was mowing my lawn on an very hot and humid day when the pain first showed up, about 2 1/2 weeks ago. The lawn mower is self propelled so it doesn't require all that much work on my part. About an hour after I finished mowing, I had bad pains in my back, that moved to my ribs below the breasts to my hands, then arms, legs and toes. As one area's pain went away, another area started up. After the toes were done in pain (a cramping pain) the pain above the ribs returned and has remained. What could this be?
