I'm sorry you have to start all over again with your testing for Cushings-- However, a swollen supraclavicular lymph node is separate from Cushings disease.
Have you had a fever, viral infection, local infection around your throat (such a tooth ache, sore throat) or night sweats? Many times these nodes will enlarge after an infection.
Physicians usually examine the lymph nodes by feeling them and characterize them based upon what the lymph nodes feel like. They could be characterized, for example, as:
large or small,
tender or non-tender,
fixed or mobile,
hard or soft, or
firm or rubbery.
These characteristics can be useful in suggesting the cause of the lymph node swelling. For example, a hard, nontender, nonmoveable lymph node may be more characteristic of a cancer spread to that node. On the other hand, a soft, tender, moveable lymph node could more likely represent an infection.
If the enlarged lymph nodes are suspected to be related to a cancer, then a biopsy of the lymph node may determine the cancer type.
Has your physician felt your nodes? Or did you just discover them?
