1. After the blessing of “Go’el Yisrael” (in which we request redemption) we say “Refa’ainu Hashem Veneirafei” (in which we request healing from all of our illnesses), as so long as someone is in pain he cannot be completely healed from his illness. The main point of the request contained in this blessing is for Hashem to heal us so that we will be healthy and strong to delve correctly into the Torah and to keep all of the commandments. (Mishne Berurah 115)
2. After healing comes the blessing of sustenance as when a person is ill he has not the freedom to request food, whereas once he has been healed he seeks sustenance in order to make his body and soul healthy. One should concentrate when reciting this blessing that we are requesting that Hashem should provide our sustenance easily without pain, in a permissible way and not in a forbidden way. (ibid)
