question: i have a hard growth on my collarbone near the centre of my chest, pain is extending from the area throughout my chest and shoulder and sometimes makes me lose my breathe...i had seen my GP last week and i had xrays..they said there are no breaks and no bone abnormalities...she just said she dont know what it is but since i seen her this past monday the pain seems to be moving. Is it something i should go see her about again or just go back in a couple weeks like she said? thanks
