I was the only patient that night, and still spent more than 3,5 hours there. I am wondering if there is any logical reason why so much time of waiting is needed. Hope it is not the deliberate politics of the hospital to discourage people to seek medical help.

The nurses were super polite and warm. The doctor was extremely kind too, and tried to be helpful. But it was quite frustrating to know that they can not make an antibody serological test for COVID-19 because too many permissions are required from the superior authorities. Basically, what I heard was an assumption that my condition is the consequence of COVID which we assume I had in March (according to the symptoms, as it was not allowed to be tested then either).
But no answer for what exactly are the complications that make me feel so bad. No check of hematological, biochemistry, and coagulation parameters. For me it is not convincing the conclusion, without specific analysis, that if a person had no thrombosis, blood clots, heart problems before, then probably she would not have them in the nearest future.

I understand the system may not care about the health of one single person, but in times of the dangerous unknown virus, I sincerely expected some more enthusiasm or at least some scientific interest in examining the patients who survived but still suffer!
