I have a lump at the base of my neck on the right side.  My doctor thinks it might be arthritis, since I have arthritis in my fingers.  I was sent for an ultrasound, no results yet.  The lump feels hard, like a bone, but I am occasionally having pain in my neck on the left, and some pressure when swollwing.  I am 49, overwieght, but have last 20 pounds in the last 7 weeks.  Firs noticed the lump 3 weeks ago.
Welcome to Chat Doctor .1. It could be lymph nodal mass after infection, of lymph nodal infection itself (lymphadenopathy), can be thyroid mass possibilities are more.2. Sinece you already had ultrasound scan done, wait for the result.3. It will give a complete picture of the lump, its nature and extensions and involvement of the adjacent structures (vessels) and so on.4. Nothing much to do now, only after the scan treatment / surgery can be planned.5. Hope it helps. Anything to ask ? Do not hesitate. Thank you.
