hi i have a quater size lump in my right shoulder blade. I could not even lay on it with any pressure because it hurt so much. It also made pain down my arm to elbow when I did any sort of work with it. The pain finally stopped after almost a year, but now on my left side in area just below my neck in back is another lump and it is causing the same problems. I go thru bouts of fatigue and sometimes get very nauseous and dizzy at times. Can these be signs of something serious. I do not have health insurance so cannot afford to go to get tests done. Thank you for your time.
