Not sure if Im over reacting, or if my doctor is being dismi

I have 6 lymph nodes in my neck over 1cm, they have persisted for over 9 months and slowly have gotten more pronounced. My doctor just called me a hypochondriac and basically told me to forget about it. He ordered an ultrasound, but not even for the lymph nodes it was a thyroid scan. My only symptom is reduced cognitive abilities and problem solving. Scared and I don't know what to do. All blood tests have came back normal. I told the guy who was doing the thyroid ultrasound to look at the lymph nodes and he remarked that all "submandibular lymph nodes were normal size. Would this include the ones on my actual neck? Just feeling the biggest one i have measured with my fingers it is over 2cm. The report of my ultrasound reads as follows; 

 

 

 

INDICATION: Concern for thyromegaly. Patient complains of submandibular neck swelling.

 

COMPARISON: None.

 

FINDINGS:

Right lobe measurements: 5.8 x 2.5 x 1.7 cm.

Left lobe measurements: 5.7 x 2.2 x 1.6 cm.

Isthmus measurements: 0.2 cm.

 

Thyroid tissue echotexture: Normal.

Thyroid size/contour: Borderline enlarged.

Thyroid tissue vascularity: Normal.

Thyroid nodules: None.

 

Other: No additional findings in the anterior neck. Nonenlarged submandibular lymph nodes are demonstrated bilaterally with normal internal architecture.

 

  • Having had thyroid cancer, I would guess they were looking for that as it often spreads to the lymph nodes and given that you don't have a thyroid nodule, I guess they can be pretty certain you don't have that. I also think, though I'm not sure, that a thyroid scan also looks at other parts of the neck, because when I got the result, the doctor basically said there were no other indications of cancer other than the nodule on the thyroid, so clearly, it looked at other things too and, given that thyroid cancer often spreads to the lymph nodes, I'd guess it looked at them.

    I don't know if there are any other possible concerns, but it's definitely good news that the scan was clear.
