Covid-19 is a weird and scary virus. It turns out that while most people report none or minimal symptoms from a Covid-19 infection, there are also thousands of people reporting prolonged symptoms. Instead of being sick with Covid-19 for 2 weeks or so (the average for mild cases), they get sick with the viral infection and then it never seems to go away. There may be big ups and downs with a wide variety of serious symptoms (including neurological and gastrointestinal symptoms, fatigue, fevers, heart palpitations), but they are still sick weeks or months after the initial infection.
What is going on? People experiencing long-term Covid-19 symptoms refer to themselves as "long-haulers" or "long-termers". Covid-19 is a new and complex disease that seems to attack many organs of the body. It is such a new disease that much is still unknown, including why some people seem to experience Covid-19 symptoms for weeks or months after the initial infection. But some possibilities are emerging, such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) . ME/CFS clusters have occurred in the past after many infectious outbreaks, including after the SARS epidemic (a similar coronavirus) of 2003.
Paul Garner, professor of infectious diseases at Liverpool School of Tropical Medicine, has documented his battle with long-term Covid-19 symptoms in the British Medical Journal blog (also June 23 follow-up), and the need for "pacing" during recovery to prevent relapses.

There are support groups on Facebook such as Survivor Corps, Covid-19 Support Group (have it/had it), Long Covid Support Group, and Long Haul Covid Fighters. Fiona Lowenstein started a Covid-19 support group (Body Politic Covid-19 support group) for people living with the virus
Bottom line: Don't let others, including doctors, dismiss your symptoms. They are real. Read about the experiences of others and join support groups. The good news is that slowly, over time, most people are reporting improvement. Unfortunately, it will take time for public health officials, including the CDC, to catch up and acknowledge what people are already experiencing.
The following are some good articles to read. Start with Ed Yong's article in The Atlantic: Covid-19 Can Last for Several Months
