The pain

I wake up and start going out side but then my lungs my organs start bursting then healing then bursting what's happening I see the demon appear and say what's happening he said you don't want the power I will come when you need not when you want pain will happen every week I say why and when it stops I go outside and start monster hunting it's not like before but I'm still the strongest i still got the speed and strength just not the other things.
