I have swollen lymph node in my right side of neck, it hurts when touched or when i click my ear. Also i feel a little nauseous since 2 days. I had mouth dryness recently since 3-4 weeks for idiopathic reasons, checked by ent and dental they said its normal. This swollen/painful lymph node came in between last 2 days. 4 weeks back i had a upper wisdom tooth extraction in that side but i had taken antibiotics for 5 days. The lymph node that causing pain is 2nd to the below of the ear on the SCM(if m not wrong the partoid or tonsillar lymph node)... So major symptoms: Pain when i clicking my ears, sometimes gum show with a dull pain for 1-2 second and go away, swollen lymph node in neck but not a lump(not visible outside), its swollen a little bit inside and painful, can be felt when palpated only, little bit stomach discomfort and nauseous feeling. Also attaching my cbc report.
