Hi..my father has 3 very soft palpable deep cervical lymph nodes( as what google calls them) at left side of neck located verticaly in a line since 2 months.. They are like boiled peas -and not increasing in size.. No pain..futhermore to mention he is undergoing dental decay and lost 3-4 tooth and root canal in past 1 year..these lymph nodes are palpable and visible only when head is tilted a bit towards right..which doctor should be consult ? They are very squishy and soft..
