Bf got hit by a car

Li

My bf got hit in the city while crossing the street , and he doesn’t have insurance so refused to let any one call an ambulance . He is in some pain and is also going through some ptsd symptoms ( trembling anxiety etc) at the moment .but he was able to get back up and go to his construction job about an hour later . Is there any way he can recover on his own or what can he do recover from a hit ?
