*sigh*

For starters you should probably stop inventing syndromes. This is a forum where people look for help with legitimate medical and psychological problems.

You are causing disproportion in your figure by concentrating muscle development in your arms. The health risks are minimal as long as you're using natural processes to build muscle, as you age, depending on how large your muscles get and how supportive your diet is you could develop skeleto-muscular issues but I wouldn't expect they'd be a serious issue. You will be teased because of your proportion, people may make assumptions about you. You're likely to face social penalties if your arms become grossly out of proportion.

More serious, you are engaged in a behavior that is causing this problem and you outright refuse to stop it. For your better health I think you should talk with a therapist about the role muscle development plays in your life and if you have a healthy relationship with fitness.
