Just do what your friend said I mean your right it might not work but it's your best chance on fixing it without going to the doctor. But if the air cast doesn't help it and it still doesn't feel better then go see a doctor!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
