In brief: Duration

Sore throat due to step or a virus will only last a few days.
Sore throat due to chronic nasal congestion can last much longer. This may be due to allergic rhinitis or possibly a sinus infection. See your doctor.

In brief: Rapid strep test...

...And/or culture will diagnose strep - which often coexists with nasal allergies (with blocked nose, mouth-breathing brings strep bacteria straight to the throat).
Allergies vs viral - allergies cause more watery nasal discharge.
