Hi everyone! I don't know if it will help anyone, but just in case it does, here is a trick to unblock your nose--
Sway your body, gently. (From left to right.). Inhale a lot of air at once, and then put your fingers over your nose, to not inhale more air. When you feel like you cannot hold your air in anymore, inhale some more and then exhale it all at once. There is a better tutorial on it(on YouTube), but this is me summarizing it.
I hope you guys stay safe, happy, and healthy!
