Post steroid use facial swelling.

My mother not diagnosed for covid 19 but on having such symptoms she get advised for defcort 6 and this is being used for abt 20 days a tablet in morning and another in evening. After stopping this, we went to a pulmonary specialist where she diagnosed with post covid pneumonia. The doctor started the medicines 10 days ago and still on medication. But still she is having persistent facial swelling. So, beside pneumonia treatment,guide me if I can consult any other speciality for facial swelling and also is there any chance of any kind of fungal infection? She is not hospitalised also not having diabetes. She is on medication for high bp I.e. embeta xr 12.5 and telista ch 80 daily and also pneumonia treatment is running. Pls guide..
