| Make sure that after she has the needle in that she doesn't apply pressure in any direction (e.g. up, down, sideways) while injecting. I've found myself doing this once in a while and it does make it hurt more. Just inject straight in and try to "hold" the needle as little as possible.
Like others have said, it does help if you are relaxed. Is she new to injecting? I use the 31 gauge pen needles and it really doesn't hurt too much. Everyone is different though.
