"they" say - don''t "work out" when you are ill. I think a walk around the block so to speak would be good for your respiratory system. Sleep when tired and try Electrolyte drinks and chicken broth or soup. CVS Clinics, if you are close to one - are good and helpful in terms of writing scripts and providing suggestion. They do testing for COVID and Pneumonia. You need to register for an appointment. They are typically manned by NP's. Feel Better - Prayers flowing your way. Also, I suppose you can always call them.
