app crasher me haha .. At first that wasn't real or something but I tried it AT MYSELF and.. it didn't go well... I felt like I was dead and can't do anything XD
I've had a lot of ear infections over years along with a ruptured eardrum, multiple tubes etc so it's really easy to do that to me I even do it to myself some times by accident
Honestly, if you can reach their face then just palm strike their nose!! That worked for me! -Study palm strikes, imagine if you miss and hit the floor or wall behind them.
Truly depends, on the comments of other videos most people say it healed after a month or so but depending on the strength or the condition of your eardrums it can vary (be sure to go to the doctor if that happens to you though)
