Hi welcome to health care magic forum,
with red and white at the end indicate epiglottitis
which present with dysphagia with sore throat
But I am still surprised that how could you saw your epiglottis because it is far behind of tongue and below it so difficult to see on mirror. It could be uvula
Anyway you can take a broad spectrum antibiotic and antiinflammatory drugs for 3 days .
If no relief see an ENT surgeon for further clinical examination and investigation.
