"Only treat one thing at a time"

When you have a illness they will only deal with one thing so you have call back or go up to hospital?! EG a fall witha bang to the head- 3 things developed vomitting, headache, a deep cut to the head, & side of the face. Could only get the headache treated and then went up to A&E plus I had to choose " which injury I wanted to them treat?" I am a whole person and needed full treatment!
