### Patient: Doctor, I have a wound on my arm caused by a recent accident. The skin on my arm and hand looks infected and feels warm to touch. Additionally, I am experiencing shoulder stiffness or tightness. What could be the reason for these symptoms?
### Doctor: Based on your symptoms, you seem to have an open wound due to trauma. The stiffness or tightness in your shoulder may be a result of the injury, and the infection in the skin could be due to exposure to bacteria. We'll need to clean the wound and prescribe antibiotics to prevent further infection. I recommend keeping your arm elevated and using ice to reduce swelling.
