Will Protein repair damaged muscles even if you arent working out?

I did some weighted pull ups by tying a bucket full of stones to my legs and using a pull up bar and now I cant do a normal pull up, because my muscles behind my arms are fully damaged and if I try to pull up, it gives away in pain and I cant seem to move. I have normal protein rich foods. Over the days I am recovering from the pain, but still cant move the muscle.Will the food that i eat repair the damage and grow the muscle even if I,m not exercising the same?
