[|Human|] I am 14 years old and I have had this really bad lower back pain issue. Also, my feet have been in pain as well as my neck. Plus, I can t stop cracking my joints. I crack everything including my toes, feet, knee, arm, fingers, hand, neck, and back. Please give me advice on what to do.
[|AI|]  Hello, I have studied your case. It is not common to have back pain at this age. I would recommend you to not take it lightly and get some investigations done to make sure that you are not having ankylosing spondylitis. For this you need to get:1.ESR2.HLA b 27 3. Anti CCP antibody these tests will inform us if there is any serious issue with your back pain. Ankylosing spondylitis is a condition in which young male suffers from back pain and stiffness. I hope this answer will be useful for you. Let me know if there is any other followup questions. Thanks
