### Patient: Doctor, I have been experiencing fever, elbow cramps, weakness in my elbow, being underweight, and coughing up blood. What could be causing all of these symptoms?
### Doctor: Based on the symptoms you're describing, it sounds like you may have oral leukoplakia, a condition that causes white patches to form on the inside of your mouth. It can cause fever and weight loss, and it's also associated with lung cancer, which could be causing your hemoptysis. I recommend scheduling an appointment with an oncologist as soon as possible to get a proper diagnosis and treatment plan.
