Damand barking & biting

Hello! I have a now 11 week old gold retriver male puppy and we have had major problems with him biting and drawing blood. And demand barking. He is not teething YET the vet says. He scruches his noise up and growls almost like it's aggressive biting. I took him to his first vet visit yesterday and he bit at the vet and the vet folded his top lip in until he pushes his finger out and never bit him again and told me to do that so he doesn't grow up to be aggressive. I've tried it at home multiple times and he just gets more angry. I feel beyond defeated, I've got bloody bites all over me still healing from weeks ago and fresh ones daily. I can't stand the barking and I can't even lay down without him drawing blood on any body part he can get to including my face. I've tried time outs and it just doesn't work. I've tried ignoring until barking stops that doesn't work either.
