I am having constant sharp stabbing pain that starts just below my right shoulder blade and radiates around under my arm under my right breast. Any movement, breathing, coughing, etc causes so much pain that I feel like I might vomit! Definitely brings tears to my eyes. I had a chest x ray about 7 days ago that showed nothing, however, the pain has gotten much worse!!! My right arm feels numb and tingles down to my fingers!!!
