First , I am just a regular btrfs user so take what I say with a grain
of salt.
However, according to the FAQ here:
https://btrfs.wiki.kernel.org/index.php/FAQ
You should run btrfs check on your filfeystem. This may be a brilliant
or horrific idea. You probably want to drop your free space cache file
as well ,but wait until a developer answers if you wanna be on the safe
side.
If you expect some serious help you should probably post the outputs of
these commands and state just for the record what distro you are using
and I am sure you will get help soon (the BTRFS list is very friendly).

My last knowledge was, that one should not use btrfs check unless asked

One should not use btrfs check in *repair* mode without being reasonably
sure it won't do more harm; and verifying that repairing is possible
usually involves developers. Otherwise btrfs check is read-only by
default and should not damge your system. Whether its output is useful
to non-developers is another question :)
