My partner had a very mild Covid (only 1 day in bed) but 2 weeks after the infection she started with the long covid symptoms. She had oxygen drops below 80% many times a day and had problems to even talk without running out of oxygen. Pain in the chest, chronic fatigue, lack of memory + concentration and absolutely all the symptoms associated to long covid. It has been a nightmare, the first GP was blaming her for smoking or not doing sport (both false), the second did some tests but he said nothing can be done and the tests were inconclusive. Finally she went to a physiotherapist who saw her condition and said that no action was unacceptable. He found a physiotherapist who is specializing in long covid, he monitors her condition at muscular level, recommends some exercises and not much more because little is known. But at least he keeps up to date and investigates. Now it’s 5 months already and she went from having the strength of a 80+ year old ill granma to a 40+ with CF… she can now walk slowly and talk without losing breath. But still her body and brain are not working even at 50% than before.
