Covid Question! Should he go in?

My boyfriend and I both tested positive on the 3rd but have had symptoms since NYE. Obviously we are out of quarantine but my boyfriend says some of his symptoms are still worsening. He woke up today complaining that he has chest pains, double vision, and dizziness. He says that the chest pains is something he’s had since earlier on but it’s worse now and the other symptoms are new. He says he’s worried to go anywhere because he doesn’t want to spend all night up there and them bill him if there’s nothing they can do. I am worried because he has been heavily vaping and smoking weed for a while and, honestly, doesn’t take the greatest care of himself
