What could be causing my upper back pain and visible bony prominence at 16 years old?

Your symptoms and the visible prominence between your shoulder blades may suggest a few possibilities, including postural kyphosis or scoliosis. Postural kyphosis typically develops due to poor posture, often in adolescents who spend long periods sitting, leading to discomfort and the curved appearance you’re describing. Scoliosis – an abnormal lateral curvature of the spine – could also cause the asymmetry and pain, though it often comes with noticeable shoulder or hip height asymmetry at well. Other conditions, like Scheuermann’s disease, where the vertebrae grow unevenly, can contribute to a kyphotic deformity too. Considering the chronic nature and impact on your daily life, and the structural changes you’ve observed, an X-ray would be a prudent next step. It can clear whether there’s an underlying spinal curve or vertebral irregularities, helping a specialist in making a definite diagnosis. Visiting a spine specialist or orthopedic doctor is advisable, as they can carry out a thorough physical exam and interpret imaging correctly. In addition, they’ll assess for any red flags such as neurological signs like radiating pain, changes in sensation, or weakness, which would need urgent attention. Depending on their findings, physiotherapy focused on structured exercises to improve posture, strengthen back muscles, and relieve strain might be recommended, alongside pain management strategies. Avoiding prolonged sitting without breaks and maintaining ergonomic positions will be essential as well. Make sure you pursue this further sooner rather than later, particularly because corrections and interventions are often more effective at your age.
