Saying Hashem can heal does not mean don’t take medicine. It means don’t worry if the only medicine for the illness is located on a faraway island surrounded by cannibals, or located in the body of someone who won’t give it up. If it is in reach, grab it. If it is out of reach, than Hashem either doesn’t mean for you to have it, or he will find a different way for you to get it. He can heal, He doesn’t need our permission.
