Hi,
There could be several possible causes for your son's symptoms, some of which are more serious than others.
Nosebleeds can occur due to dry air, allergies,
high blood pressure, or injury to the nose. Vomiting can have many causes, including infections, food
poisoning, and certain medications. Chest pressure while breathing could be due to a respiratory infection, asthma, or a more serious condition such as a
pulmonary embolism.
Given that your son is experiencing multiple symptoms, including chest pressure, it would be advisable for him to seek medical attention as soon as possible. He could start by seeing a
primary care physician or going to an urgent care center, and they may refer him to a specialist depending on their assessment. It is important not to ignore these symptoms, as they could potentially be indicative of a more serious underlying condition.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Priyanka, General & Family Physician
