I have had a sore throat for over a month. There are small white spots that won't go away. I tend to cough at night when I go to bed.

Yes, it is possible for some clinics to diagnose symptoms similar to COVID-19 through teleconsultations. However, it would be best to consult a doctor in person to confirm the diagnosis and receive appropriate treatment. You can also take acetaminophen or ibuprofen for the pain while waiting for a consultation.
