Those symptoms are not the same as Covid.
Just sayin lol
I know someone who got sick with a infection fever some blood loss but not left threatening. He he came in alert, super smart, taught himself calculus, really good in psychology, physically fit has more than two different black belts in martial arts, taught weapons, gourmet cook to get a idea, only in the hospital a few days, came out with memory loss, severe weakness, needed intense care for needs. They just discharged him that way like here’s your husband back. There in another state so hard to assess but looks neuro.
A doctor told me years back things are getting bad knowing I was famous for not going to a doctor or the few times for injuries to release myself before they did told me seriously and very seriously to find a good doctor and hold on to them. He over saw things.
In the meantime take care of your health.
