Brief Answer: Investigations required. Detailed Answer: Hi, I have gone through your query. You haven't mentioned the site of injury or from where the popping sound came from and if there is any associated external injury I assume, based on inability to use a arm and pain during breathing, that it is on shoulder and chest. But it is important to know if muscle or bone or both are affected. For this a clinical examination is required. If muscle injury, usually rest and muscle relaxants are advised and in severe case(tear) surgery may be done. If bone Fracture, X-rays will be advised and reduction is done. I advise you to see a orthopedic doctor for clinical examination and investigations like X-rays. In the meantime, NSAIDs like Ibuprofen can be taken for Pain and give rest to affected part. Hope I have answered your query. If you have any further questions I will be happy to help
