I had the flu starting 5 days ago, with a high of 102 F 4 days ago, and resolving since then. Last night I went to bed with no temp, no nasal congestion , and normally sized tonsils. Woke up this morning with GIANT lymph node. Anterior cervical. SO huge I can t swallow . Super hard. Super big, like golf ball sized. One side only. Palpating makes me nauseous. Where do I go? urgent care?
