My experience, starting about 5 days after she showed symptoms was more or less the same without the sinus pain. The fever broke after 2 days. The fatigue has been the primary issue and I have apparently lost about 5% of my body weight since quarantine began. Losing your sense of taste and smell seems to correlate to not having an appetite.
Our two young children ~7 years old are ok. One had sinus pain for day, but a warm compress helped with that. I assume they have it and we are all quarantined inside as a result.
Feel free to ask further questions.
