Differentiating between cold sores (Herpes Simplex) and Canker Sores? - herpes on hand picture

I read that herpes simplex in the mouth (hard / soft palate, inner cheek, tongue diagnosed ..) as a throttle to be. What are ways to make a difference? I suffer with cold sores, that outside the mouth in the oro-facial skin occur, and I'm afraid I'll give it my friend. I agree with her cups, dishes, I make sure my hands are clean, not embraced, at least up to a week after I'm sure he's gone. In summary, I am) very closely. I heard him complain of sores in the past, and I know that it is not uncommon among people without any kind of virus. Now, as I shall read this misdiagnosis, and I saw the pictures (which are not really helped, they are just pictures, after all), I'm a little paranoid.
