<s>[INST] Hello I am having pain deep inside my shoulder. It has been long term pain. It started about 5 years ago. I did 6 months of physical therapy. It got better but has recently been much worse after throwing a lightweight ball at a high velocity. It is like a deep achy pain. It gets fatigued very very easily. With certain movements it feels as though it is sliding in and out of the socket. There is also tenderness. I have meloxicam from a previous injury that I have been taking, but it has not made any difference. [/INST] Hello, As per your history, it may be due to blunt trauma. For pain, you can take tablet acetaminophen. You may require X-Ray of the affected shoulder for detailed clinical examination. After orthopedic consultation. Restrict your movements. Use support while walking. Further treatment mainly depends upon the underlying condition. Hope I have answered your query. Let me know if I can assist you further.   </s>
