Hi. I have a mass or lump on the back of my neck and I am experiencing pain, numbness/tingling in my shoulder blade area (both sides) and down my back. I have headaches if I do anything physical to include general house cleaning, pulling, pushing, throwing a ball, lifting objects or working over head, etc... I have had this for several years but it has worsened over time. A neurologist did a CT scan and it did not reveal any tumors, etc. He thinks it is just fluid ...fatty tissue. I have been on a prednisone medidose pack twice within a five week span. The swelling is the same. My rheumatologist did a ultra sound today but I do not the results as of yet.
