Here is another new thread w/ pics showing a foam roll technique - You can even start flat on the floor is pain is bad, then move up to rolling a towel to use as the roll and then if you want move up to ball or foam roll.

I started out on the floor (per Sharon Butler's TOS program) Like the yoga corpse pose. Then saw the rolled towel idea so moved up to it, then an advanced PT told me about the foam roll use, so got one of those.
I adapted the exercise ball as a change up.
