I tested positive for covid 9 days ago. im now on day 7 of persistent fatigue and dizziness. the dizziness is making me miserable. it comes in waves but persists for most of the day. how long will it take for this to go away????

It's hard to say exactly. Your symptoms are certainly consistent with the range of symptoms caused by COVID-19. At this point, what you can do is rest and make sure you are drinking plenty of fluids, and try to eat. Without knowing more detail of your medical history, it's hard to give you more specific advice. I would recommend contacting your doctor to discuss further.

You may wish to consider that you may have long COVID. It would be prudent to contact your local medical school as there may be doctor's specializing in this emerging disorder.
