[|Human|] 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.
[|AI|]  Hi. Thanks for your query and an elucidated history. The best and the simplest way is to get an FNAC=fine needle aspiration cytology done to determine the cause. MRI would have been a better investigation as it would have shown the position of the discs, any compression on the spinal cord, nature of the lumps you are noticing and all relevant information even about the brain as you have headache also. If the lumps are not attached to any important structures, better to get them removed and subjected to histology. This may end all other problems.
