### Patient: Doctor, I have been experiencing a lot of pain lately. My hand, fingers, shoulder, neck, and even elbow have been hurting. I also have some low back pain. What do you think is the problem?
### Doctor: Based on your symptoms, it is possible that you have brachial neuritis. It is a condition that affects the nerves in the shoulder and can cause pain in the hand, fingers, neck, and elbow. The low back pain could be related or a separate issue. We will need to run some tests to confirm the diagnosis.
