I have a very large 'nodule' on my sternum. I also have a previously diagnosed (in 2011) thyroid nodule. I was originally diagnosed and treated for Graves' disease in 2011 and quit treatment (due to being broke) in 2013. A couple of months ago, I noticed that my sternum felt uneven... One side was way taller and lumpier than the other. It is not visible though. If I flex my stomach muscles, you can see another (maybe the same, but I hadn't noticed until I became concerned with my sternum nodule) underneath my ribs on the right side. It is VERY large. I am usually tired, I get full after eating very small portions (like maybe a quarter of a sandwich) when a few months ago, I could put back a whole pizza. Please help. I'm nervous and my dr hasn't been much help. Already had X-rays that came back normal, and he said come back in 6 months, but I REALLY REALLY think something is wrong
