[|Human|] I am very worried about my 14yr old son. He has been extremely tired, sometimes irritable, complaining of back pain and headaches, loss of appetite. Tonight he had all these symptoms plus a nosebleed... Why is he experiencing this? What should and can I do to help him?
[|AI|]  Hi Welcome to Chat Doctor After going through your query I concluded that your son may be suffering from vitamin deficiencies or some chronic disease. He needs to get his tests such as vitamin B12 and vitamin D3. He needs to investigate by blood including hemoglobin, ESR, kidney function test and chest rays. Furthermore, he needs to visit physician. You can discuss your doctor about it. Hope your query get answered. If you have any clarification then please don't hesitate to write to us.
