I am being treated for c diff with flagyl (10 days); just noticed swollen neck, no other symptoms beyond slight pain at base of ear, jugular; can't feel any nodule (but, then again, I'm not a dr.), also take Victoza for Type II Diabetes (on/off for 3 months.  Concerned about medullary thyroid cancer.  Thoughts!

Summarized question: Could swollen neck be due to medullary thyroid cancer?
