I am a 33 year old woman who has been experiencing pain on my lower right ribs frequently for the past seven years. No doctors can seem to figure it out: I ve had ultrasounds of all the organs in that area and everything checks out, and I just had x-rays of my ribs that showed no fractures, dislocations, or problems with my heart or lungs. The ribs toward the inner front edges are extremely sensitive to the touch. When the pain happens, sitting or,lying down and taking 2 Tums are the only things that help but I would like to find out what is causing it so I can treat the underlying cause, not just the symptoms. I drink approx 3 liters of water a day, have a healthy diet of whole grains, lean meats, vegetables, and healthy fats and I m a college student so I get exercise walking around campus and I also swim and do strength exercises at home.
