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; cant feel any nodule (but, then again, Im not a dr.), also take Victoza for Type II Diabetes (on/off for 3 months.  Concerned about medullary thyroid cancer.  Thoughts!
Hi, Thanks for writing in. A swollen neck for 10 days is unlikely to be a cancer. However, a complete clinical evaluation and further screening of cancer is advised if your swelling in the region of the thyroid and neck region. Medullary cancer is a subtype of thyroid cancer. Please note that more than 80 percent of swellings of the thyroid are benign and do not indicate cancer. Pain in the base of ear and jugular vein area can be nonspecific. I suggest that you relax and consult the ENT surgeon. Please get neck ultrasound and thyroid function tests if required. Lymph nodes can also get enlarged in the neck. Doing a complete blood count and peripheral smear as a part of routine investigations can be done. Please do not worry.
