@joanng Did they also do a sputum culture for MAC (mycobacteria aviums complex) - often MAC and pseudomonas coexist and both need to be treated with completely different meds.

Also, multiple rounds of antibiotics can leave you with fatigue, and you are correct that they may not have cured your original infection.

With multiple health issues, it is quite reasonable to request accommodations to continue to work from home until there is a vaccine for Covid. I believe it qualifies as a reasonable accommodation under the ADA.

Eventually, once they get the infection(s) under control you should begin to feel better.

Have you been monitoring your oxygen levels? Very hard to function if they are low.
