Praise be to Allah.
It is Sunnah to learn ruqyah as prescribed in sharee’ah, seeking to benefit the Muslims and treat these chronic diseases, because the Book of Allaah is a beneficial healing. But it is not permissible for a non-mahram man to touch any part of a woman’s body when doing ruqyah, and it is not permissible for her to uncover any part of her body such as her chest, neck, etc. He should recite over her even if she is covered, and this will be of benefit no matter where the pain is. It is also Sunnah for some of the sisters who can read Qur’aan to be taught how to do ruqyah so that they can use it to help modest women. And Allaah knows best.
