Covid negative. Chest problems. Too.

Around 40 days ago, my mother suddenly came down with breathlessness in the middle of the night with no prior symptoms. The breathlessness alongside a chest heaviness continued on and off for 10 days before we consulted a local GP who prescribed some antibiotics. When this didn't work, we consulted another physician on the 20th day who gave her a long list of covid medication (favipiravir, azithramycin, ivermectin, doxc, ecospirin, etc). These continued for 10 days. But breathlessness didn't completely go away. We consulted another GP who prescribed her injections for 2 days (mikacin, dexona, Deriphyllin) and a 10 day course of omnacortil 10. The breathlessness has now gone away for 7 days but she has started to show other symptoms like mild chest pain, low urine, tightness in the centre of the chest. 2 days ago, she suddenly had lightheadedness in the morning. And today, she felt chest pain when she talked a little loud. Breathing and eating cause feeling of tightness in chest too.
