Primary symptoms of active tuberculosis include all of the following EXCEPT:

Active tuberculosis is primarily characterized by respiratory symptoms and systemic manifestations that reflect its infectious nature and the body's immune response to the infection.

Night sweats are commonly reported by patients with active tuberculosis, often accompanied by fever. This symptom is a result of the body's response to the infection, as it attempts to fight off the bacteria causing tuberculosis.

Fatigue is another prevalent symptom associated with active tuberculosis. The infection can lead to a significant decline in overall health, energy levels, and endurance, making patients feel unusually tired.

Hemoptysis, or coughing up blood, is a serious symptom associated with active tuberculosis. It results from damage to lung tissue due to the infection and is an indicator of a more advanced stage of the disease.

Joint pain is not typically considered a primary symptom of active tuberculosis. While some extrapulmonary forms of tuberculosis can affect the joints, this is not commonly seen in pulmonary tuberculosis, which is the primary form. This distinction is important, as it highlights that the other symptoms mentioned are directly tied to the respiratory system and the systemic effects of the disease itself, while joint pain does not align with the classic presentation of active pulmonary tuberculosis.
