Hello! Can you be more elaborate about his complaints. Chest pain in his case can be due to something very common like GERD (Reflux disease) or it can indicate something to do with his heart or lungs. Since when is he having the pain ? Where exactly in the chest does he have the pain ? is it continuous ? is it mild or severe enough to disturb sleep ? Any particular thing that you have noted to aggravate or relieve his pain ? Any other chest complaints ? Does he smoke ? Looking forward for an elaborate history. Since you mention soreness all over , it seems more likely to be reflux disease in which case he will need medications to control that and needs to avoid spice n caffeine in food, head end elevation during sleep Do consult a physician in person too.
