Hi. I am a healthy 45 year old female. Last week I was doing some weights. I didn't feel like I overdid it. Two days later I had a pain on my right front rib which hurt to the touch. It seemed to travel to my right side. And this weekend I went for a walk and felt something pop in my back. Pain went from front, side to back. Now I'm in severe pain. Not sure if it was a muscle pull or something more.
