Hi my name is Shane 23 y/o, I have a lump on the left side of my collar bone, it is painful but at first I felt pain on my left shoulder for two months then this lump showed up, its been here for a month and now I feel a lot for uncomfortable feeling no matter what I do walking and standing up for a long time makes the pain worst, I already went to the doctor but still got no result, I went through CT Scan, Chest Xray, Blood Test, TB Test and still got nothing, and now they want me to to a neck ultrasound and biopsy.. I can't sleep comfortably anymore because of the pain.. I am feeling a heavy pressure on my shoulder and on my head.. doctors think that I have TB but I don't have the symptoms of whatever, is it possible that you have a certain kind of disease even if you don't have the symptoms? Maybe somebody out there has the same feeling as mine.. please leave a comment.. thanks
