Suggest Treatment For Pain Between Shoulders And On Rib Cage

Hi i have constant pain between my shoulders and my skin feels sore. I also have rib pain under the top quadrant of my rib cage. have been suffering almost 2 years now. Had xrays to see if it was gall bladder but everything turned out fine. Have psoratic artritis. Am trying for a baby, but am afraid in case it's something serious.
