Hi! this is another fairly common clinical situation in our routine patients and not to worry much regarding this!
In fact, considering your medicine history along with
thyroid lump, I would like to extend my comments as follows:
1. there is 90% possibility that the nodule in the nape of neck is a lymphnode recently enlarged in response to some inflammation in the
scalp, skin, throat,
axilla, ear etc. or related to medication...!
2. some benign subcutaneous tumor-like condition like
neurofibroma / lipoma/ dermatofibroma/ inclusion
cyst comprises of 8% possibility
3. some malignancy or borderline tumor pathology have 2% possibility
No biopsy/radiological study of thyroid lump? It must be there; please share that also!
Therefore you have to see your doctor not because you are worried but to confirm what is it and for some tests like needle biopsy...
regards,
