### Patient: Doctor, can you tell me what's wrong with me? I have these weird symptoms like mouth ulcers, frontal headaches, temper problems, arm stiffness, and a swollen tongue.
### Doctor: Based on your symptoms, it appears that you may have primary immunodeficiency, which means that your immune system is not working as it should be. This can cause various symptoms, including recurrent infections, mouth ulcers, and swollen tongue. The other symptoms you mentioned may also be related to the immune system dysfunction. We'll need to run some tests to confirm the diagnosis and start the appropriate treatment.
