swollen cervical lymph nodes

I had an mri done of the neck and it showed scattered enlarged lymph nodes under 1 cm. which were described as non specific, non aggressive, no necrosis.  My ENT says that is no big deal.  Blood work does not show any infection.  I also had a thyroid ultrasound which showed a 7mm hypoechoic nodule.  The endo said that we would repeat the test again in 6 months to keep an eye on it.  Neither doctor seemed concerned about either finding.  Looking for opinions.
