In this location, it's not visible outside but when i palpate, i can feel that pea type lymph node. Its firm but it moves, slight pain when pressed. Apart from that, occasionally i feel that area a little stiff/tensed. Which goes away with massage. All blood tests normal. All these problems are arising after a viral infection in first week of January. Before that nothing was there. Also, I am suffering from insomnia out of nowhere. Please guide me what to do. Apart from those above symptoms nothing else i feel. Please help
