### output:

Hi. Thanks for your query. Read the history in detail and understood your problems. Pains in the right and left rib area, top of belly for one year, Doctors trying to tell this as gall stones, stomach ulcers, blamed pregnancy, X-rays and blood tests and ultrasonography all normal, MRI refused. The probable cause of such a pain with negative ultrasonography can be"Prolapsed discs in the thoracic region. You need an MRI of the spine. Another reason can be Costco Chat Doctor.  MRI helps here too. You are taking so much of codeine in spite you have a small baby. Be careful before taking any medicines as you may be breastfeeding.
