I have a lump in my right shoulder. The size and texture change daily. It can be small and soft, or hard and larger. It has not really gotten any bigger over the last couple of months (had it for going on four months now) and I have been diagnosed with Lupus since September. This lump is painful to the touch and sometimes even if its not touched. I also have swelling of lymph nodes under my right arm, on the right side of my neck, and behind my knees, but the one in my shoulder bothers me because Im scared of what it could be. It goes down to almost nothing at night and when I get up and start lifting stuff, cleaning house, or moving around it swells up some. But like I said it has not gotten any larger. I have noticed lately that I have veins that start at the top of my right(same side) breast and extend up my shoulder and across my chest. They look like someone has written on me with a marker. I am fair skinned, so to see veins is not unusual for me, but these are dark and prominent. I am really scared of what this might be caused by. Any insight would be greatly appreciated.
