Re: intensely cramed or intense cramp
Do you mean you felt very confined in the space you had, or you experienced a muscle pain?
You don't have "a little intense."
I felt intense cramping in my abdomen.
My tiny room was too much. I needed more space. I felt intensely cramped -- like I couldn't even stretch out my arms. I had to get out of there.
My small room felt smaller than usual. I felt a little cramped, so I went for a walk.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
