I just saw this study which seem to be more and more confirmed that say the covid infection can have long lasting damage, mostly on cognitive function and tiredness etc

So don't understimate it because the symptoms are low and doesn't look dangerous, i would strongly advise to take any measure you can to heal as fast as you can
