Here I suggest if it is a long standing problem do check with the press at your bony prominent area like front of your legs also called as shin border as well your arm level and wrist level and rib level but not the one which is already paining. If you experience pain all over this bony prominence then it indicates weak bones as well vitamin d deficiency. Because when we press the bony prominence with light pressure for normal individual usually it won't pain. This is my own way of testing physical. When some body need accurate result they can always go for lab testing and bone mineral density test.
Now foe your case I suggest if it's paining on bony prominence all over body then start calcium and vitamin d tablets. And also use heat pack on your regular lower rib pain to have soothing effect. This way it will give you good relief. You can check with other ultrasound scan for abdomen pain and take appropriate treatment. Take care.
