Hello, I came down with a mysterious illness in 2013, around the time of Mers, that left me short of breath, with palpitations and fatigue. I am an asthma patient, but this was not the shortness of breath that comes with asthma. It seemed more related to the heart. I finally started recovering from fatigue when I got on to Ashwagandha herbal capsules. I read recently that some corticosteroids which work for asthma are effective for treating covid too. Ashwagandha is supposed to contain some naturally occurring steroids within it. You could try it, since it worked for me. With best wishes, Malan
Are you following up with your doctor? I'm not sure if you're saying you had covid 6 weeks ago, or if for 6 weeks, you've been testing negative for covid?
If you had covid, it can cause lung damage, so you need to be working with your doctor to determine if that's what's happened to you.
If you have high WBCs, that can indicate an infection or inflammation. Have they done a lung x-ray? That would be the first thing I ask for, if that hasn't happened yet.
If you're saying you've had covid and still have symptoms even though you've long been cleared of it, from the interviews I've seen repeatedly on the news and in the newspaper join the crowd.
