May be a virus - but: For significantly sore throat w/ swollen tonsils/lymph nodes – see physician & get a strep throat test & culture. Antibiotics are imperative for strep throat. Try saltwater gargles. Mix tsp of salt in 8 oz of warm water – gargle w/ this several times/day. You can gargle w/ Aloe Vera juice a couple of times per day. A mix of chamomile tea w/ honey & a small amt of lemon juice helps.

Yes: Yes. A medical evaluation would be indicated. Also in the meantime treat with NSAIDs, saline gargle, soft diet.
