### Patient: Doctor, I have been experiencing side pain and weakness along with difficulty breathing. I also have some back pain and leg pain. Can you please tell me what's wrong with me?
### Doctor: Based on your symptoms, you may be suffering from pulmonary embolism. This is a condition where a blood clot forms in the lungs, which can cause pain, shortness of breath, and other symptoms. I would like to run some tests to confirm the diagnosis.
