Your xray seems to be normal. Kindly go for a video consultation.

Rule out acromioclavicular subluxation. share xrays of both shoulder.

Hello, The x ray looks pretty normal. Pain at such an young age is usually due to abnormal biomechanics at the shoulder girdle unless you have had an injury. I am a shoulder specialist myself. So would advise you to visit a physiotherapist who is well versed with shoulder rehab. However, it would be better if you can provide more details of your problem. You can always have a formal video or audio consultation with me if you feel that it is required. Hope this helps
