<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello doctor, I came here because I have a severe injury to my shoulder. Its been hurting non-stop for days and I can barely move my arm.  <response>: Im sorry to hear that. Based on your symptoms, Im prescribing you with a few medications. Youll need to take Ketoprofen and Diclofenac Topical Product to reduce inflammation and pain. Additionally, Alfentanil may be needed for serious pain relief. Lastly, Cisatracurium Nimbex is a muscle relaxant that you might need to take to help your shoulder muscles rest while healing.
