I have been diagnosed with an autoimmune disease called Morphea. I was given a prescription called Metrotrexate. This disease has affected my skin. I get red patches that look alive every summer. With this medicine it has calmed it down a lot. Last night I woke up with a severe sharp pain right below my right breast cavity traveling to my backside and shoulder. and especially hurts when I take a deep breath or Lay down in a certain position. Does anyone recommend anything or have any ideas what this pain can be?
