I have had a dry couch since saturday and i am extremely tired. i also get dizzy at times and feel nauseous. is this something to worry about?

Cough & other sx's: This cough could be from a number of conditions (& COVID 19 is one of them). I would request assessment by your PCM so it can be determined if you need to test. In meantime, quarantine. COVID 19 sx’s: dry cough, shortness of breath, nasal congestion, fever, headache, sore throat, feeling tired, loss of sense of taste/smell, decreased appetite, nausea, diarrhea, vomiting, chills & muscle aches.
