I'm really worried about my 16-year-old brother. He's been having this sharp pain in his chest whenever he takes a deep breath, and it's been going on for a couple of months. We initially thought it might be because of junk food, but he's actually stopped eating it for about 8 months now. I'm trying to figure out what could be causing this pain when he breathes deeply. Could it be something serious? What should we do about it?
do chest xray and proceed further
