question: Hello doctor, I am a 44 year old female. From the last four days, I have a pain when I breathe in. It is felt just above my left breast, not exacerbated by lifting, but when I stand up from a lying or sitting position, it gets worse. I also have a slight ache in the left shoulder and on the top of my left arm. I am not taking medication. The pain is not relieved by anti inflammatories or codeine. I cannot recall injuring myself at all.
