I get the pain in the rib cage area a lot. Mine is in the left rib cage, in the lower part.
I get the constipation more than the other.
When I get those darn "knots" popping up, I also press and massage them deep down and they eventually calm down and go away for awhile.
My psychologist told me yesterday that it is classic for someone w/fibro to go to the dr's telling them that one day they'll have pain "here", and the next day they will have pain in a different spot.
If you have really bad pain in a certain spot one day, you need to think about what you did the day before. One morning at the beginning of my journey w/fibro my chest,arms,shoulders were soooo stiff and painful. Then I remembered that I had made a pie the day before. Rolling out the crust is what did it!! I couldn't believe how just making a pie effected my body!!
I can't tell you if you have fibro, but your story sounds very familiar.
