Hello and welcome to HCM,
 From your prescription i understand that you are diagnosed with 
multinodular goitre, and cervical lymphonodes. The multinodular goitre is a very common pathology in the population. 
 The next step to do in your case is to measure the 
thyroid hormones level, in order to see if these nodules are active or not. Scintiscan would be of help too in this case.
 Most of your nodules are small (1 cm, with suspicious elements in 
ultrasound (hypoechoic, irregular borders,  microcalcifications ect) and who are 
cold in scintiscan we do recommend fine needle 
biopsy aspiration. 
About the lateral cervical lymph nodes, there are not enough elements described (their shape, vascularisation ect).
The familiar history is also very important in diagnosing suspicious nodules.
There is also a tumoral marker called thyrocalcitonine that gives important informations for thyroid  nodules. 
I hope the information will be helpful for you and i am opened to answer any further question.
Best regards,
Dr.Guni
