Hi DR. I am a male, 52yo and weigh about 280lbs. I have been having a problem with muscle pulls around the upper outer edge of my abdomen. if I reach/stretch too far or bend over too far I have intense pain in an exact spot. it happens mostly around the upper outer area of the abdomen. It's like the slightest twist or turn and the muscle grabs. Sometimes it takes 15 minutes to relax enough to move into a better position. I know I have to lose weight. Is that the problem? Kevin
