question: I have tightness in my back on the right side, tightness in my chest and pain under my right breast, Im having a hard time breathing. Taking breaths is hard, any movement is worse. I can't cough. It feels like Ihave stuff building up in my chest but I cannot cough to get it out as the cough cuts my breathing off.  I've recently been treated for sinitus and bronchitis.  Should I go to the ER or Urgent care?
