I have swollen lymph nodes along my digastric muscles and collar bones (palpable and on CT scan) and they have been this way for over a year. Should I be concerned? I have odd symptoms such as dizziness, weakness, tingling in hands and feet, My most disturbing symptom is the feeling that my swallowing is altered like I have a huge lump in my throat. My CT also says that I have non-specific prominence of my thyroid with a palpable fatty tissue overlying.
