My 14-year-old sister's been having these sharp pains in her left arm and chest. Sometimes her back hurts too, and even her jaw is in pain. I'm really worried about what might be going on. What should I do?
It sounds like your sister may be experiencing symptoms that could be related to a heart issue. It is important to seek medical attention immediately. In the meantime, you can give her a tablet of Aspirin 325mg to chew, which can help in case of a heart-related emergency. Encourage her to rest and stay calm while waiting for medical help to arrive.
