It sounds like you have a viral syndrome
of sorts. It could be an ear infection
that has invaded the throat or vice versa.
Usually, these sorts of episodes of illness are transient and otherwise uncomplicated. If you have a high fever
or cannot hold food or drink down.
If you are severely vertiginous (the world is SPINNING not just "dizzy/lightheaded") and have nausea/vomiting
or are experiencing any specific weakness in an arm or leg that you've never had before THEN, under those sorts of circumstances I believe an ER visit would be reasonable.
Otherwise, lots of hydration, eat something soft or bland in case you still have a sore throat
and all of this should pass within a few days to about 1 week or maybe a bit longer.
Hope I have answered your query. Let me know if I can assist you further.
