Day 11 today. Was bad enough to have to be checked out at hospital two days ago as absolutely racing heartbeat. Had full checks and sent home with instructions to go back if worse. Yesterday I felt a lot better though with some vertigo. Today I still feel a lot better though earache from coughing and nose blowing. But mostly I feel scared as have read so much about how things can get better before they get worse. Anyone know how you can know if this is coming? Heartrate back to normal now and oxygen levels are ok.
